Just picked up a TF Denka, no experience with the others unfortunately, and here are my thoughts:
1. I got to choose between two, and opted for the heavier/beefier copy. It’s substantial, but still well balanced (both were, actually). Mine does not seem to have an overgrind on the blade road, which was my main concern. If it’s too fat, fine, I can take metal away, but it can never be put back.
2. The other knife seemed to have a distinct overgrind near the heel. This is the version the shop would have sent had I not inspected myself. It is a bit challenging to check, but worth the time.
3. The handle’s not a looker, the spine is harsh, and it’s ugly where the bolster meets the blade.
4. I don’t give a damn. I can round these with sandpaper and a block on a slow weekend if I care to.
5. It whispers through food. That slick, convex stainless jacket over a hard-as-nails blue core (a metal blend that TF has apparently designed himself, if you believe the legends) means that the knife burns through produce like an Australian Bush Fire after a summer drought. I mean, Jesus. It’s got the Top Gear x-factor for me. I don’t want a cigarette, I just want another onion to murder.
6. Food release isn’t the best (my Kochi and Carter (not Muteki) are better). But, it’s pretty damn good, #3 of many. This was also true for the shop’s test cutter TF Maboroshi.
7. I think both the Maboroshi and Denka would be fantastic. It was my birthday after a big health scare, so I splurged on the Denka.
All that said, I’ve never touched either other knife you’re considering. Grain of salt, mate.
