Ittosai Santoku rehandled

Tue May 15, 2012 9:45 pm

I got this one years ago. It's an Ittosai Santoku from Hida Tool, it was around $30 when I got it way back:

Changed the handle out to this with Stabilized Koa when I got it, but the blade was too thick and liked the wedge in foods:

It met the belt sander today :) I flat ground the top 2/3-1/2 of the blade, convexed the bevel and brought the bevel up a bit from where it was originally. This helped thin out the knife, but it's still pretty heavy! It had some deep hammer marks/pits in it from the Kurouchi finish, so I left a few because they were deep:

Cuts much better now!! It's turning a nice blue/purple after cooking a steak, slicing it down the middle, then sticking the blade in between the layers for a few minutes. Yeah, I'm weird!

Bead blast the rest of the older finish and you won't have to grind and smear it with red rare steak juice. That will get rid of the marks. Btw where did u get the handle I love that. Jmbullman

Some assembly required :) I figured out a Wa style handle finally :) This was my first attempt with the aluminum tubing like this. The ferrule is a synthetic piece that looks like Honey Horn I got from Masecraft Supply (kinda like plasticized pearl stuff), copper spacer and Stabilized Spalted Maple Burl. I used a piece of aluminum tubing to help join the pieces together, then ground the tang down to fit into the tubing :) It's an oval handle, much easier to do than the Octagon style Wa handles!

I was going to bead blast it, but it is so purty when it gets all blue and purplely and gold!!! I am a sucker for the patina :) I have a friend with a blast cabinet, so this and the Tojiro ITK I reground will both visit the bead blaster to see how that changes the patina and how food reacts to it.

I'm a sucker for punishment :) I got the Addict 2 and a couple other Wa style knives from Mark and decided to try to figure out the Wa style. The Redwood Burl/Buffalo Horn Tojiro ITK was the first real attempt and the method worked, but it was a pain to do. Trying to glue and clamp 5 different pieces really sucked, especially because they needed to be clamped in 2 directions! This method is much simpler, easier to clamp, etc. And I can do up the handle and then fit it to the knife after I grind the tang down. Right now, I kinda like my Wa handles a bit bigger and more hand filling. The Addict 2 handle is just a tad too small for me. I build fishing rods and use my fingers a lot with the thread work, and my hands tend to fall asleep easily (carpal tunnel maybe??? :( ), so the bigger handles feel more comfortable to me.

Took like 20 pics, no luck on getting the blue and purple to show for the patina :(
