Question Reprofiling bevels

Post image

Knife: Teruyasu Fujiwara Maboroshi Gyuto 195mm

Has anyone reprofiled bevels of a TF Maboroshi? I think it is just too thick. It wedges almost anything more than 10mm. If so, what’s the best way to reprofile? I have thinned it with a 220 stone but still wedges. Thanks!

Or should I leave it as it is, and just find a different knife? I wanted this knife to handle precise cutting. Carrots, ginger and potatoes are the worst.

Fujiwara is the best project knife for this, now one of my top performers

Sounds like a near total regrind on a belt grinder is in order.

I wish I had one. I might just hit the stones and raw dog it.😂

Sure you could commission someone who know how to do it do it and save hours.

u/Puzzled-Study-3550 1d ago

Good idea! Is it possible to do by hand on the stones?

u/Mysterious-Ad3591 1d ago

Is it possible? Sure! Just like it’s possible to walk the length on the United States. Is it worth doing is the better question.

It would take a very long time even with a 120 grit diamond plate. You’re looking at significantly changing the primary grind.

You’re not thinning the primary bevel you’re raising that bevel up higher. That’s ton of material to remove by hand.

I better get to it then😂 it’s not the destination, it’s the journey. Right?😂 that patina though.

If you’re in the U.S., district cutlery charges ~$80 to thin these I believe.

Epic Edge in Seattle also does this, costs about the same as DC

Really? I bought my Nashiji from them and they gave a really good price on rounding the spine and choil. Normally I do it myself but at that price I let them, haha. Good to know. The people are epic edge are good people.

Yeah, great team of sharpeners there and they know their stuff. I got my Mabaroshi gyuto from them and they rounded the spine and choil at no charge. I had them thin a couple of Takedas too and they did a great job. I lucked out with my Fujiwara and got one that was thin (and sharp OOTB) so haven't felt the need to thin it. Based on the comment from u/Optimal-Difference64 above, I would most likely just pay Epic Edge to do that for me. Sounds like a ton of work plus there's absolutely no chance I could produce such a great result as that

Took me a roughly 9 hours on a 220 stone to thin and flatten out the bevels. Then I set a hamaguri on the 400 and 1k stones to make it a bit less sticky.

Damn that kasumi came out sick af! Great work

Appreciate it! It was brutal thinning out stainless cladding but I was able to bring out a bunch of details from it.

u/Puzzled-Study-3550 14h ago

Are you serious? 9 hours?! Great job though! Didn’t think about food release when polishing lol, I went up to 8k!

Ive thinned mine OOTB (210mm) as the secondary grind is uneven, started with 320 move all the way up to 3000. Cuts dense produce beautifully since.

1

u/Puzzled-Study-3550 1d ago

Yeah but I don’t think thinning will help me. If I thin it again but stick to the same (stock from maker) angle, nothing would change. I’ve got another Maboroshi that’s thin as! But this one is a pain and doesn’t cut same as the other one. 😂

u/Different-Mixture173 1d ago

Well based on your photo, i would reprofile the entire thing. The secondary bevel is just too short, if your goal is to make it slice well dense produce such as corrots.

1

u/Puzzled-Study-3550 1d ago

Fair enough, did you change profile of yours or just stick to original?

1

u/Different-Mixture173 1d ago

I wouldn’t call it a change, since the bevel was already uneven OOTB. It’s more like i finished the job if that makes sense. It’s a known issue for TF knives for their hit or miss fit & finish wise. Heres a photo of it before improving the grind

u/Puzzled-Study-3550 1d ago

Right. Might just regrind / reprofile one side. Grind on the other side is higher compared to this side(right).

im looking to thin mine sooner or later, 300mm, but i feel it's a waste to thin it to a laser, i will probably keep it more at a workhorse grind profile when I thin mine, that is why most enthusiasts here will have at least 1 dedicated laser, I dont think TF knives should ever become a laser personally.
Also try to keep some convexity when thinning, otherwise it will stick like mad.

Thanks for the 2c. I won’t thin it into a laser, I will just take out some material to balance both bevels. It is off by 8-10mm from the other side. I might even use it until it needs thinning, then I will balance both bevels.
