V Grind Japanese Kiridashi He-Man Frame Lock

Seen here is the first true V grind model of the Kiridashi blade that I've bought from Japanese Woodworker. Again these are sold as folding craft knives and I won't get into why I like converting them to something a little more user friendly again. Thats covered in the other threads. Anyway, this is done and working but its needing a good break in and its been a bit of a learning curve to work out how to get a decent action since the detent ball in the lock is rolling over hammer marks on this blade compared to the ones I've done in the past that I had not run into this on. Its a bit of a trick to make differentially heat treated blades work in a folder anyway you cut it but I've done it several times now. The hammer marks go back further on these double bevel blades too so that didn't help. Its a bit of a bumpy ride as the ball bearing works a trail on the blade but its smoothing out little by little with use. In an effort to make it less noticed I used a 2mm size ball bearing in the lock after a friend gave me the idea that it worked to use bigger tires when rolling over rough terrain. So on this one as opposed to a 1/16" ball like I normally use I bumped up the size. It has helped some too. I've used double washers on each side to reduce some friction in the action and I am running that dry for the time being to break it in faster.

I figure I'll leave this one for a couple of weeks to see how it goes and if its still not as smooth as I like I may have to cut some deeper more profound lock cuts into the lock to ease up on the pressure the lock exerts on the blade as its rolling open and closed. This is something I hope is not necessary as I really prefer to make the locks as stout as possible with as minimal a lock cut as I can get away with. With this one however, the detent ball will call the shots as to what I do down the road. Otherwise what a blade! I really like the V grind model and I think overall performance will be more in line with what I've grown used to all my life in the normal style edges I carry. I sliced some with the blade last night using it on some hard wood and wow what a great blade! It slices like a dream reminding me of some of the better Scandi grind blades I've used! Of course they all do work well from Japan Wood Worker but this one is particularly satisfying since it is a true V grind as opposed to the one side grind models and I so love the look of the hammer forging marks on both sides of the blade. On this model I did include a low rider clip for right hand tip up carry. Some of these pics came out a bit blurred. Sorry it was getting darker by the second and by the time I got em loaded on the computer well, it was too late to take more and they show the knife well enough to make out the general details. This folder is sold. Thanks for looking.
