Making a few tanto like knives fo my next project. Blades are 1075/80 hardened at 1500f and tempered at 500f. The fuchi and kashira like parts are bronze. The wood for the tsuka is red maple I think (I always use scrap wood). Here thay are so far- "One little, two little, three little ind..." "I said tanto, not Tonto." "Oh."

By 1075/1080 do you mean that they are of the two steels laminated? Also, are they forged or purely stock removal, and what did you use to shape them?
lookin good.

Looks good BB, that a faint hamon on the top on perhaps? What was the quench? If you used oil you might not have gotten them to fully harden IE giving them an accidental hamon. If you want to try for some clay coat, drop the 1075/1080 down to 1450F, soak for 5 minutes then quench in a fast oil or water if you feel lucky:D, interrupted quench only, 4 seconds in the water 1 out 3 in then into warm oil, that'll give you a wild hamon, no need to temper at 500 unless you want SUPER tough blades, you can score a bit more edge retention at about 450/475, give it a try it's really all personal preference though. Those look great.

Thanks Random, Dark and Master ;D I had more pics of the blades taking shape (as well as a couple sword blades) but they were lost when my old computer died. I thought about taking pics of the grips in process but didn't really think that was very interesting. Next time I'll know better.
Slavia631, Admiral Steel lists the metal as 1075/80, I assumed that means that the carbon content of the batch varies from .75% to .8%. Purely stock removal. I cut out the basic shape with a plasma cutter and refined it with an angle grinder then the rest was shaped with the angle grinder, an air grinder, hand-held belt sander, DA sander, and lots of hand sanding.
Sam S, Quench was ATF. I was actually trying to get a hamon and had clayed the blades. Wasn't sure of the process though and didn't end up getting any so I think that's just an illusion in the pic. I'll definitely try the method you suggest next time, thanks for the advice!

Admiral 1075 will produce a hamon in oil but it will be faint and indistinct. Polish them up to 3000 grit and then give an etch in lemon juice for about 1/2 hour.

Thanks, I'll try that too on one of these. Here's a bit more progress-

Not bad, not bad. Do you have any plans for wrapping the grips or will you leave them as they are? Perhaps a stain?

Stain would look pretty nice I think. If it dosent turn out good you could always then just wrap it afterward.

Thanks guys . I'm planning on wrapping them. I don't know if you can tell from the picture but I made the bronze fittings a little larger than the wood so that when I wrap them they'll be flush. Should be done and have pictures by tomorrow. Couldn't find 3000 grit wet/dry anywhere today so I had to stop at 2000.

I did notice the size difference and that's exactly what prompted me to ask. How do you plan on wrapping? Solid leather, tennis-racquet tape, cord wrap, maybe some tsukamaki?

Here we go, all finished. Here's a picture of the blades... And here's a picture of the tsuka... The two tsuka on the right have the standard Ito Maki no Katana type wrap. For the smaller one on the left I thought I'd try Tsumami maki; it does a good job of hiding the fluffy backside of the leather strips I used for ito (which you can see sticking out like a sore thumb on each twist on the other two.) I wasn't sure how secure it would be compared to the regular wrap so I only did the one that way. All three use the gunto style knot though I had to cheat a little on the small one as I was trying to use up a strip of leather that was a tad too short. The knots also didn't usually happen to end up on the correct side but I figure it's not like they're really traditional tanto anyway. And here's a pic with the lighter for size reference.
