This is no Jolly Roger, but it looks grim nevertheless. I do not think any other part of human skeleton is more evocative than skulls. And I wonder sometimes whether this is a purely a cultural thing, or whether there is something innate in us that associates skulls with death, danger and general unpleasantness. There might be, because our brains are clearly predisposed to recognizing facial features.

The four dots at the jaw bones – bellow the eye sockets in each maxilla and two on the chin on mandibula – and two dots above the eye sockets are points where the nervus trigeminus exits the protective shell of the skull to innervate facial muscles. That is why these points are more sensitive to pressure than other parts of the face. Professor Kos told us that an inflammation of this nerve is allegedly the most painful illness there is. The whole face hurts and a feather caressing the cheek may feel like being burned with hot poker. One way to reduce the pain in very severe inflammation cases (I do not remember whether this was an old procedure or one or still in use) was to inject a powerful neurotoxin directly into these points. Extremely painful procedure, but one that provided the needed long relief. He told us the patients would scream and sometimes pass out. And the neurotoxin used? Alcohol.
Nervus trigeminus is near surface once more just behind mandibula, right bellow the ear lobe. This knowledge has helped me twice in self-defence, once when I was held in chokehold but I managed to slide my hand to my attackers head and drill my forefinger into this point and second time when another person was having their arm twisted by a wannabe teenage ninja. The pain is so intense, that anyone will let go of anything they hold and try to get their head dout of the way. If you feel brave you can experiment on yourself. I did. I do not recommend it.
When the weather is not suitable for work outside, I will make use of my belt grinder, now Mark 2. So today I took another old file and I decided to make a dagger out of it. The inspiration is dagger used by Vesemir and Ciri in the game Witcher 3, but there will be some design changes even for the blade (less daggery, more knifey). I will post my progress, but beware that I am no expert, just a self-taught hobbyist goofing around. Risk of concussions from facepalming for any expert. You have been warned.
I started with an old file that I threw in the stove fire last year to soften the steel. I cleaned some of the rust on the belt grinder when I was testing the new design. But before proceeding I needed to make the tang slightly longer. So today I just made the tang more pointy and chamfered the edges. Then I took an old piece of round stock of structural steel, cut it lengthwise for a few cm and fitted it onto the file tang.

After that there came the trial by fire, or more precisely, electric arc. My first real welding. I admit I should have tried to simply weld scraps together a few more times before I try for something real. I should have. But learning skill on something that is subsequently thrown away simply is not me. I always try to learn on the real thing. Not smart, I know, but that is just me. I have already forced my self to try it once on scraps.
I must admit, I could not have done a better job. That is to say, the job is crap, but I lack the skill to do better. But it holds together even after grinding off the slag and rust from the whole thing. There are some visible slag inclusions in the weld, but it is definitively welded together and since it will all be hidden in the handle, I will not lose sleep over it. Hopefully no rampaging rhino will stamp on it and ruin it all.

Cleaned and the tang ground to rough shape.
With that done I finally could do some work on the belt grinder. Since I do not have machinist’s blue, I used 1 cm thick blue marker to cover one side of the file. Then I have drawn the center line and quarter marks using a steel ruler and a self-made steel marking needle. After that I ground the file into a symmetrical leaf shape. With that I was done for the evening and I will resume the work at some other random date.

I do not remember why I drew this, but based on the paper on which it is drawn I did it at home and at my computer desk.

I have to pass on the Iron Curtain series this weekend, because my mind and my hands are now fully occupied by work that won’t wait – repotting my trees. I only have this weekend for the deciduous trees and next weekend for the conifers, because after that the trees would be too grown and I would not be able to touch them without risking they die as a result. Which I do not want.
Currently my trees are more about quantity than about quality, because creating high quality bonsai takes time and I am only doing it for twenty five years. The plan is to build up stock now and refine it when I retire. Growing bonsai trees is not something for the impatient. But I have some medium to good quality ones already and I will share pictures. (I also have trouble getting my hands on quality bonsai pots, because they are not sold anywhere near and I am reluctant to buy them over the internet).
Here is a glimpse into the work that I am currently doing:
It starts with buying a load of coarse sand and spreading it out to dry in the sun. That does not need to be done, strictly speaking, but I find it easier to work with dry substrate so I try to dry it as much as possible. Another ingredience to the sand is high-quality soil or compost, sieved through a 5 mm mesh and also dried if possible. And last ingredience is peat or some suitable substitute, like shredded old leaves and moss and twigs, or maybe even saw dust. The organic material is there mostly to hold moisture and stop the substrate from clumping.
Next step is mixing up the substrate. Because I have a lot of trees and other potted plants, this used to be the most time consuming and tiring part, taking up hours of hard work. Nowadays I am doing it in a concrete mixer. A great saving of time and strength, I do not understand how I could manage without it. I was younger, healthier and I had less money but more time on my hands, so there’s that.
Whilst I am mixing suitable ammount of substrate, lets say 100 liters or so for starters, I also have to scrub and disinfect all the pots and bowls that are currently not in use. That is, I take them out, rinse them with boiling water and let them dry in the sun. That seems enough, I never had problem with fungal infections or rotting roots. I do not have enough pots to replant all trees at once, so I have to repeat this process multiple times as pots are emptied.
When the pots are ready and the substrate mixed, it is time to take out my most important tool case. Have fun trying to spot all the tools that are in it. All are used for tree care. And just in case someone can decipher the writing on that lid in top left corner – that is not actual mustard, just the cup in which once was mustard. Now it is full of charcoal to treat big cuts on roots.
I think it is time to get out the macro lenses. There were a lot of these on the pond at the end of my sewage disposal facility. I also saw a first butterfly at work and a first toad. The toad was in the plant, on the road where forklifts are driving so I took it carefully outside, over the road and into a grove.

Over the years I have expressed in multiple comments under various articles on FTB that whilst strict regulations of access to weapons are necessary, the strength of the regulations should be proportional to how effectively enforced they can be. Regulating automatic guns makes sense because they are difficult to manufacture and conceal. That makes it possible to effectively limit access to them and enforce the regulation in a meaningful way.
On the other hand I have always seen trying to regulate knives, swords and similar as absurd because such regulations just cannot work as intended. Making a functional knife or even a sword is trivial, all you need is a piece of cord, a flat bar of any type of steel whatsoever, and half an hour work with angle grinder. Sure, it will not be beautiful, and if the steel is crap it will not hold an edge, but that does not matter, it will be effective murder weapon of equal quality to what was used most of history in warfare. And concealing a knife on your body under clothing is trivial.
UK has nevertheless decided to pass such a meaningless regulation:
Luckily I am not living in UK and CZ has not jumped the shark yet and knives are completely unregulated here. But should such laws pass here, I could perhaps get into problems when trying to buy certain tools for my hobbies – for example I intend to work with leather at some future date and for that I will need to either buy or make a few specialized cutting instruments, aka knives. I live in rural area and I definitively have no corner shop around that could supply those things on demand.
I feel sorry for all the antique weapons dealers and all the knifemakers in UK – like the excellent Tod Todeschini, whose carefully build livelihoods can be destroyed in an instant with ham-fisted regulation.
I might add that to my knowledge this regulation has been proposed and written by conservative politicians. Similarly like the US knife regulations, which are stricter than firearms regulations in some states, were too written by conservatives. Laws that are either impossible to effectively enforce or are impossible not to break serve no other purpose than to give police a pretense to for example harass people of inconvenient shade of skin at will, nothing more.
And just for “fun” (which is not funny at all) I will list all the object that could be used as murder weapons and are in my line of sight right now, near my computer:
Not to mention the about 8 kitchen knives of various sizes on the kitchen counter behind my left shoulder.
If I were to go to my workshop or my garden shed I would have a wide choice of multiple potential cutting or stabbing weapons, blunt instruments and pole-arms. Should I decide to go and join a gang, I would not be unarmed. Indeed I could arm the whole gang. So could each of my neighbours.
Whilst firearm deaths can be linked to firearms availability, stabbing deaths cannot be linked to knives availability. Because stabbing instruments are everywhere and will be everywhere, always. As Sam Vimes’ maxim states “Everything is a weapon if you decide to think of it as such”. Addressing knife crime needs to address the root cause. And I do not think I am stabbing in the dark here when I say that has more to do with impoverishment and disempowerment than with sending knives per post.

Two short videos comparing two different types of medieval armor from practical point of view. One by an enthusiast owning a medieval armour replica in European style, and one by an enthusiast owning a medieval armour replica in Japanese style. Both armors were made specifically for these individuals, so they are fitted as well as they should be.
A lot of the things I learned in school about medieval armor and swords was evidently completely wrong. Like that armor restricted movement so much that it was impossible to move quickly, or that swords in Europe were blunt metal bars out of poor quality steel.

This was the first iteration of my belt grinder. I built the whole thing out of scraps and it was completely ad-hoc process – piling stuff upon other stuff as it seemed appropriate at the moment. The base is a piece of thick particle board – specifically the piece I had cut out of new kitchen counter for the sink. Further I used a few other cuts of particle board I had lying around and an old 1,5 kW motor from old pump. The tracking wheel, the drive wheel and the platen I got from a cheapo 60,-€ belt grinder that I bought specifically for those – I expected it to be useless and I was correct. The guiding wheels I have built each out of two ball-bearings, a piece of threaded rod, a piece of metal tube as a spacer between those bearings and a stainless steel furniture leg as a shell. The furniture leg did not pass tightly over the ball bearings but I was lucky enough to find for 10,-€ a plastic tube that filled the difference perfectly. The guiding wheels were then fixed between two scraps of plywood together with the platen in hard belt + slack belt configuration.

The tracking wheel was a major headache for me. I had everything done but I still did not know how to do that part. As I was mulling it over in my head I got the idea one day whilst driving home from work. I have used a garden gate hinge (a new one, because there was no suitable one in my scrap pile) on which the wheel is fixed to the short wing and the longer wing can rotate. The angle between the hinge wings can be adjusted by a screw going through the long part and pushing against the part that holds the tracking wheel. The force for tension was supplied by a spring from an old bed. The spring ws too long so I had to bend it around a strange wheel of unknown origin.
It has worked reasonably well, after all I made two knives on it and I ground the basic shape of a machete. But mainly it was a proof that I can do this and that it will work. The machine as seen on these pictures does not exist anymore. I have completely rebuilt it and only the base and frame have stayed unchanged.
Caine seems to be stuck at the hospital, lets hope it is not serious.
So I am posting today’s bird instead. A lovely lady chaffinch.

Human hand has always fascinated me and its skeleton is truly a marvel. Modern industrial robots still lose a lot to its flexibility (hands have seven degrees of freedom of movement, robots have one to six) and versatility (a hand can have a secure grip on almost anything from an egg to an axe).

For learning and examination we did not have a plastic skeleton mounted on a stand in the corner of the class. We had a box in which the real prepared bones of a man who committed suicide at a relatively young age were stored. So each bone could be taken out and examined separately.
One of the scary stories circulating about Professor Kos was relating to this fact. Small bones, like carpal and metacarpal bones, were stored in little pouches so they do not get lost or too mixed up with the rest. It was said that Professor Kos’s favourite way of examination in his former job at medical university was to shake up the pouch, pull one carpal bone out of it and ask which one it is. Any aspiring physician who failed to give prompt and correct answer was fired.
He did not do this to anyone of us that year, but we always felt he might to.
