Big ol katana

[Sam Salvati]

After a long hiatus, I had some projects move forward a little. A big camp knife and a stock removal katana.

Ground the bevels, the precurved the katana, no clay, quenched In parks 50 and tempered in my super secret squirrel tempering oven I do all long blades in. Wasn’t going for a Hamon, just after that archetypal Wally Hayes style tac katana. Will attach photos as soon as I figure out how.

wondering what % of curvature folks expect to lose in oil with no clay vs clay

I look forward to some pictures. I did a stock removal katana myself a couple years ago.

Basically, you upload them to imgur and then post the bb link that imgur provides.

Looking forward to your katana!
I’m curious if you’ll lose some sori when quenching in parks 50 vs brine or water.

interesting, i have never heard of that. i thought it only happened with water.

I get negative sori with DT-48, which is a hair faster than parks 50. The slower quench rate in the second half of the quench causes the negative sori, where the faster quench in the second half of the quench in brine causes the sori.

Hey!! After your comment on your oven above and your comments in my oven thread.... fess up some pix of your oven as well!!!

I overcorrect the sori by about 25% in grinding/forging and it seems to come out OK with Parks #50.

Reading comprehension is apparently not your strong suit, as stated I don’t have an oven and hate them so can’t show a picture of something I don’t have or use.

I’ve done a few brine quenches when working with John Lundemo, an exceptional craftsman with a very high success rate in brine quenches. You always gained sori, so was best to go into heat treating dead straight and let the brine give you that wicked perfect curve

Water gives you positive curvature, oil tends to un curve things. If you go into oil with a straight blade it usually dips forward, clay or not

So I don't know you, or your sense of humor or sarcasm. Here's a few tidbits about me.

I do run an investment firm, a tax practice, an estate planning firm and I graduated summa cum laude in English and Economics dual major.

I'm midway thru a PhD in finance engineering, though I don't know that I give a shit about that now thats schools are too liberal.

Reading comprehension isn't usually my problem.

I'm just looking around for ideas about how people temper long blades in their homemade ovens. Everyone has access to different resources and I don't want to spend buckets of money when I can salvage.

Tony, Sam doesn't mean any harm. Sam has been around for a long time and is a talented smith. I don't know if I ever saw a person who could swing a hammer like Sam. He is both blunt and funny. He also is a man of few words, and gets to the point fast. When he was younger, he used to be a wild man, but now age has mellowed him. .... somewhat.

I'm sure he's a fantastic smith. Surely infinitely better than me. but until he learns how to post a pic on line, he probably shouldn't tell anyone they can't read!! No harm done.

Where's the LOL emoji when you need it

Sam's stuff has been posted on TV in the Man at Arms series. He doesn't need to post a photo here for people to know he is talented. He has worked for the last several years in a large ornamental blacksmith shop in NY.

Got you covered

Apparently not. Nevermind.

That’s awesome.
I’m sure it’s a huge pain in the ass, but I would love to see a video of the build or a wip.

He doesn't need to post

I remember when Sam was an active member here. Honestly that doesn't excuse bad manners. I totally respect his abilities, but stand firm on respect that should be shown regardless of the skills of an individual.
