I use Tandy swivel knives that are at least 25 years old,one I have is from my dad and it's close to 40 years old. The blade I think has been working best for me, lately, is a cheap hollow ground 1/4" Made in Japan blade from Tandy! I recently ordered my first Barry King beveler and am waiting for it to come in. Will it make an actual difference, or will it just seem that way?
