Due to luck, fate, fortune, and persistant nagging, I was able to buy a santoku-style kitchen knife from Larrin Thomas at the end of a passaround knife review. The knife is just over 11" long and its blade is just over 6.5" long and 2.125" wide at its widest. The edge is 0.01" thick near the ricasso and thins to about 0.006" near the tip and the spine is just over 0.09" thick near the handle and 0.025" near the tip - that's as thin as some edges!

The steel is Bohler Uddeholm AEB-L heat-treated to RC63 and the handle is made from green linen micarta. The spine is eased and the handle is very comfortable. Please excuse the reflection of my stove's ventillation hood in these pictures:

Note that the blade has more belly than most santoku knives may have. Just like on Shun's Elite 8" Chefs Knife, this lets you get more cutting area out of a small amount of blade space. Coupled with my small arms, it works very well for me. Oh, here's a picture of it with a chef knife:

The chef knife in question is called a Nenox S1 240mm gyuto and its blade is the standard for thinness in stainless kitchen knives. Larrin Thomas' santoku is slightly thinner!

As I said, when I first got the knife, it had been in a passaround. One of the folks was a sharpening expert/addict/guro, one was a professional chef, another was a sharpening expert/addict/guro-to-be, one was Nick, and there may have been more. The knife was steeled, chopped hard, and then subjected to all manner of high-grit waterstone and uberhigh-grit lapping film for over a month before it saw me. The result was that I got a knife sharper than I sharpen, but it had fatigued steel on the very edge. So that dulled quickly (in the middle of dicing a bag of onions! Not fun!) and needed its edge reset.

Remember how I told all of you that its spine is as thin as most edges near the tip? While setting the edge with a coarse benchstone, I bent the tip. It's fine now, but the temptation to mail the knife back to Larrin along with every other knife I own (and any sharp pencil) was strong due to my act of stupidity. Yes indeed. The tip is now straight, the knife is now sharp, the finish is now scratched - the knife is now mine.

Some things I really really like about this knife are how it glides through everything without effort and lets me perform precision work. The green linen micarta handle was expertly executed and its grip improves when it's wet, so that's a big bonus, too. Whether it's trimming fat off steak and peeling potatoes or making pineapple Christmas trees, it's a true champ.

I think Larrin Thomas makes one heckuva knife and hope he makes more. Your hands hope he does, too.

Thanks for reading

Disclaimer:

Larrin Thomas's heat-treatment of AEB-L to a hardness of RC63 is very labor intensive. Do not expect the maker of your favorite $40 folder to heat-treat the same steel in the same manner without the price-tag rising to well over $200 for the same $40 folder to cover all of the extra labor. AEB-L is generally, and specifically as Larrin Thomas heat treats it, a fine-grained steel with fine carbides which make up a small percentage of the steel's volume. It takes and holds a very finely polished edge at a small angle. I've seen SG-2 steel do the same thing at a similar hardness despite it being the polar opposite. The place where the theories become reality involves angles of about 5-6 degrees per side with polishes exceeding 8,000 grit and no microbevelling. At that point, sharpening becomes insanely time-consuming and the ability of a low-carbide steel to work better in those tight parameters than a high-carbide steel are necessary only so far as preventing suicide from the thought of resharpening is concerned.
 
Maybe after I've made some more knives I'll be able to make something really nice. I'm glad you like it so far. With how little experience I have the future is very exciting as I see it. I hope others can share in the journey by enjoying my knives. With so many small flaws so painfully obvious to a novice knifemaker (or at least to me), it is nice to hear so many positive things from those who used it in the passaround as well as from Thom who now owns it.

Hey! I had nothing to do with how that knife turned out... In fact I only used it to cut ONE piece of Pound Cake.

But... it is a very nice knife. Congrats.

Looking forward to some small carbide comparison reviews.

A very good disclaimer. I've guessed for some time now that the claims of low carbide steels and the issues claimed with higher carbide steels have been greatly over stated, and aren't a factor with most all tipical knife edges. Another good review, thanks.
 
I really liked the knife when I got to use it. I got it with a tree topping edge that had only been steeled and stropped by a professional chef who used it extensively prior to me. I cut up some apples, onions, and tomatoes (a lot of them) with it and was really impressed. The edge retention wasn't as good as my Takeda Gyuto in Aogami Super Steel, partially due to the steel at edge being fatigued as Thom said, but the ergonomics, fit and finish, and cutting ability were top notch. The sharpness came right back on some lapping film and I think a 8K waterstone (I don't remember if I used a stone on it, but I think I did), but it really needed a full sharpening and the fatigued steel remained when the knife got to Thom (but at least it was passably sharp). Sorry it ruined you onion dicing, Thom. I knew Thom would obliterate the existing bevel with his D8XX anyway, though. Congrats on such a nice knife and letting me use it. And many thanks to Larrin for making such a fine piece of cutlery.

One three meter piece of abrasive-impregnated latex poundcake. I understand.

Actually, only brought you up because when I was mentioning being tormented by its pending arrival and you posted a pic that let me know it had been used by more people than I had thought and because the picture made the torment more excruciating.

Don't know how it compares to other knives with small amounts of carbides as they're all other shapes.

Gunmike1,

The edge was sharper than any I have ever made, but it's back to life if even with only my 8K 'working' edge.
 
Well I guess you'll have to learn to sharpen for real if you really want to benefit from AEB-L, Thom. :rolleyes: For the record I can't get a knife near as sharp as those guys either. Lots of practice and stones left to buy first.
 
It's pretty sharp now; dull compared to the edge it got from gunmike1; but pretty sharp and hold its edge throughout two pineapples and regular cooking.
 
I doubt it was sharper when you got it from me than it is now Thom, but it definately needed a full sharpening to get to some fresh steel, all I gave you was an aligned burr I think. How does the sharpness and edge holding compare to your Takeda and Nenox so far now that you got to fresh steel? I know for me it was nice not to have to immediately wash and dry it after every food group like with my Takeda.

I haven't used it enough to compare it to the Takeda or the Shun chef knives and have even less time with the Nenox (it's finally replacing the Suisin), but it cuts like both and I'll probably find myself resharpening it while it's still very sharp like both. Just tested and it will whittle hair on my arm. The spine-to-edge grind on it is just outstanding.

More 'western' handled knives need that linen micarta; specifically green linen micarta (only because I like the color - all of the linen and canvass micartas behave similarly so far as I've seen); as the fabric part of the handle expands when it gets wet while the phenolic resin stays put so it gets grippier when you need it.

Thanks, jaislandboy! They tasted even better.
 
Thom, you seem to have made a lot of posts about knives cutting pineapple. Is this just my imagination or do you really like pineapple? Kind off topic and I hope this isn't some kind of taboo question to ask, but I'm just wondering. Pineapple tastes good.
 
New edge used several times cut onions with no slipping, no problem, and barely any force (like a li'l guillotine). Edge retention is not a problem when the knife doesn't get steeled. Much like most high-hardness steels.
 
Thanks for reading

Thom, indeed, thank you for writing. You don't know me from father Adam and I seldom post, but I read everything you write for the sheer pleasure of it. I would say 25% of what you write is immediately useful to me, 25% stretches my extended grasp, and 50% is enjoyed for your pure wordsmithing agility which certainly meets and possibly even exceeds your acumen with a metal edge.

Within these fora, manly brusqueness would appear to be the consensus. I feel as if I have already exceeded the limits accorded the Beta doggies under the porch and so Hats Off to you and your Kick Out the Jams attitude toward the written word!

Natch :thumbup::cool:
 
Just out of curiosity, did anyone else notice the hardness was 63 HRc and the tip bent and was straightened instead of breaking off?
 
Thanks for your kind words, Natch.

Me2,

Grind any steel; at any hardness; thin enough and flexibility isn't an issue. I have a fully hardened 1095 parer from Alvin Johnston that I hollow ground even thinner than he goes and the edge flexes when I touch it up with a Spyderco DoubleStuff.
 
I've never seen one of my tips break, it could happen I guess.
 
Thom, where are the grind lines on the blade? I cant see them in the pics, and I can see from the handle shots that the handle doesnt appear ground. Are the grind lines cleverly and expertly hidden just at the edge of the handle slabs? The visible and diagonal grind lines were always a source of frustration on my Camillus chef knife. The handle was split when I bought it as a second for $3, and I could never get the new handle to match the lines and completely hide them.
