Hi Everyone,

It's been a while.

First, I really like Ohta. I've purchased directly from him for quite a few years. When I visited Japan in 2017 I picked up one of his small, basic friction folders at a knife shop in Tokyo. As you know, that model is only in the $50 range. I wanted to see what it would be like carrying a friction folder and made a deal with myself that if I carried it for a year I'd upgrade to his fancy model. Well, I really like carrying a friction folder.

I started out carrying tactical designs in the 1990s (in my 20's) and moved to traditionals sometime in the early 2000's (in my 30's). Now I'm into friction folders (pushing 50). Guess I'm getting old.

Anyway, how bout some photos... These are just over 3" closed and both have D2 blades.

So, it's been over a year and I was ready to order one of Hiroaki's higher end friction folders but he's out of ironwood. My buddy who is a world class woodmaker hooked me up with some very nice Koa that was from a tree in Honolulu. I've sent that off to Hiroaki to make me some knives.

In my search for friction folder pics I came across Mr. Kotoh's work. Evidently he taught Hiroaki how to make knives. I was so impressed with his take on the friction design that I ordered the above model directly from Japan. The cost was over double than Hiroaki's knife but still very reasonable. It arrived yesterday and I'm very happy with it.

Now I've got to decide on what type of steel to use with Hiroaki's new folder. I was thinking of trying the VG10 damascus but after looking at a bunch of photos I'd rather something plain.

I never had much experience with D2 until Hiroaki's friction folder and it has been outstanding. It takes a hair popping edge and holds it. My cutting is pretty much limited to envelopes but and light stuff. But, the D2 has outperformed pretty much everything else I've used in the past. That's quite surprising. It does take a lot more effort to initially sharpen. But after the initial part it's been easy to touch up. I don't like rust...but the D2 has not had any issue with corrosion.

Or, I could go with ATS-34. I think all the charts would say ATS-34 is a better choice for edge holding, ease of sharpening, etc. But, has anyone else had really impresive experiences with D2 vs ATS-34 / CPM 154? I'm leaning towards D2 again but would like to get some input before making a decision.


Isn't this a pretty little knife? I love the blade profile.

Wow Paul, that is a beauty. Kotoh is a master. What type of steel is that? Looks like you could shave would it. Very nice.
 
Big Dave Big Dave I'm far from a steel expert but my experience with CPM154 has been very positive. I dislike something that is difficult to sharpen but of course want a lasting edge. I find that CPM154 splits the difference between a lasting edge vs. ease of sharpening suitability well for me. It easily sharpens to a razor's edge and holds that edge better than I actually need. CPM154 has become my first choice in cutlery steel whenever it is available. BTW nice friction folders.
 
Although I'm not personally a fan of FF the quality of the Kotoh's shown here is outstanding. Great choice of Stag and other materials and I agree, the blade shape is superb.

My dealings with Mr Ohta have been remarkable, he does what he promises to do, at the cost quoted and on time. Few professionals are like that, unfortunately... He has my greatest respect.

I'd opt for D2 or what the maker recommends-that is what they will make well. Thanks for this thread, beautiful knives on a tiresome Monday morning;)

Regards, Will

Thank you! Yours are very nice indeed, not seen that with those scales before :thumbsup: I see Fendrihan your side still stock them.

The blade on mine - sorry, I forget - but it is a very subtle damascus or san-mai. Bit embarrassing that I cannot tell, but it's very subtle, will try get a better pic (very likely san-mai)

Good advice gents. I think I'll go with whatever Hiroaki recommends.

Paul, I registered on your forum. Looking forward to checking it out.

Have a great week.

- you're most welcome too :thumbsup::)

There's a wee bit of a meltdown on there just now, please ignore, hopefully it'll all blow over fairly soon...
 
Hi Big Dave,

Am primarily a balisong guy but do partake in friction folders also. Have you seen the works of Michael Morris and David Sharp? Both make friction folders where the tang is... a beer cap opener! (friction multitools)
 
That's a great combo. I like beer and I like knives. Thanks, I enjoyed looking at them.

One of the coolest custom knives I owned was from David Lespect in France. It was a friction folder and one of the sharpest knives I've had also. He is a great craftsman with an excellent sense of design. The blade was carbon steel and I was afraid it would rust...so I sold it. He's one of the top makers in France.

Although it was a friction folder it had a locking mechanism and seen below...the two springs had ball detents if I recall.

I had an Ohta friction folder, an FK5 like the one in your first photo. I love friction folders!

For ideas on what you want you can google Ohta Friction Folders and click images, lots of sold out models but beautiful for sure. The Desert Ironwood models are my favorite since he usually uses burl.
As far as steel I doubt I would lose sleep regardless which I ended up with. The one with the hammon line is particularly attractive.
There are a couple of blade shapes but thats a personal preference thing as well. Please post it up when you get it. I love the stag model you posted.
 
I'm going to bring this thread back to life with this:

Ohta FK 7 Friction Folder with Cocobolo Wood frame and D2 Steel blade.

Super smooth consistent, firm, action from full close to full open and back again to full close. Smooth finish - slick to the touch. Accompanied with a very nice leather slip.

That one looks really nice Ed, I just recently got an OHTA FK7 in Ironwood, really liking it. Very well made knife and agree on the action, he really has this knife nailed to perfection. :thumbsup:
 
I love H. Otah's work, I once had the chance to get one from his own hands and it is a true favorite. Mine is a slipjoint.

I have no problem with friction while open, but that protruding bit annoys me a lot when closed.
Both your knives are outstanding. Just not for me, but I'm not the only one in the world! :)
I am a donkey about steels, all I can say is that HO's D2 is on par with Queen's, talking edge keeping or ease of sharpening.

Here some ffs by Richard Ciachera, outstanding work by another golden person (same show btw). (we call FFs piemontese)

No, you're not trolling the thread. Thanks for the pictures.
 
Big Dave Big Dave , I was too new to BF back then. Would not have appreciated such a knife. I have matured in my tastes ;) A beauty for certain!!
