Today I fix up my coworker's Japanese santoku knife. It was full of chips and nicks and he was finding it hard to use in the kitchen. Hopefully after the repair he will find it a little nicer to use. I also fixed up the handle and the tip so that its comfortable in the hand and hopefully the tip wont break again. I used a 400 and 1000 grit diamond whetstone to grind back the defects and then polish and sharpen the blade.
The way I fix up the blade may not be the way everyone else does it or even the best way to do it but I tried my best.

Thanks to Coastal Archery for giving us a great time and allowing us to film inside. The staff were very helpful and wanted us to have as much fun as possible.

Today we talk about separating the hand and the feet in swordsmanship. Were back with another clickbaity title, but its not to say kikentaiichi as a concept is wrong, but more the way its taught is often too rigid in saying that the hands and feet must move together and things could be far better if we separate the two depending on our intention.

Today I try and make pool noodles harder to cut! Ill be practising rokudan-giri on the pool noodles and then I try and increase the difficulty by making some small modifications to the pool noodles. Pool noodles are cheap and easy to use as targets and make little mess so they are a great tameshigiri target, however, they arent very hard to cut if you have good edge alignment. So today I try and make them harder to cut and well see if it works.
Swords-T10 clay tempered wakizashi 55cm blade length
Tameshigiri targets
-Pool noodles-these require good edge alignment or they will not cut, very little power required. Also pool noodles that have been bent or manhandled have their fibres break and become incredibly difficult to cut as they have a tendency to bend instead

Today we dive deep into the topic of blade sharpness. How do you tell if a blade is sharp or blunt? For the last two weeks I have been hung up wondering if there is an objective measurement for blade sharpness and trying to come up with one, turns out there is one that has been around for over a decade; blade edge radius and in this video I will talk about what it is and if it matters to knife and sword enthusiasts sharpening their blades.

Heres a snapshot of my first 8 kata, I still havent learnt all 12 but its a good picture of my form at present. Plenty to improve upon and plenty to learn. Even just watching this video I can quickly spot my mistakes. Fixing them is another matter though.

Bohi and boshi are both parts of the Japanese sword, be that a tanto, wakizashi, katana or nodachi. However, theres a lot of confusion around which is which and what they do. Today Ill hopefully clarify which is which and their functions and debunk some myths while Im at it.

Today we talk about striking a balance in historic fencing. Do we push for progression or strive for preservation in historic sword martial arts? We discuss how HEMA has found a balance and how we are yet to achieve this for Historic Asian Swordsmanship, looking at case studies of Koryu, Kendo and XMA and how all of these lack balance but achieve their goals. Hopefully in future we will see more HEMA like clubs training in Asian Historic Fencing.
