I hear and I forget. I see and I remember. I do and I understand.
Now that I've mostly flattened the bevel, the thing seems to be an excellent anti-stick cutter with only slight wedge tendencies in thick stuff (it wedged in the raw 8cm carrot butt that I showed, but that's a little extreme). I might work on the asymmetry and final convexing a little to see if I can optimize it, but it's doing pretty well so far:
Not trying to be overly serious here, but I wasn't inferring anything about not knowing how to drive stick or being a wack new driver.
I am saying you buy an M3 cause you know it's sick value for the money and a super fast, sick, fun car. You don't buy it expecting a Ferrari, but you do know it has the potential to literally match a Ferrari's performance with less cache if you send it to an elite tuner like Dinan or AC Schnitzer and dump $70K+ into on top of the sticker price.
So when you buy a knife like a Takeda, although you know it won't ever reach it's full potential if you don't either know how to put it to the stones yourself or send it to an ace pro sharpener, you still expect it to be straight tight out of the box. What you don't expect and shouldn't accept is it being comparable to some $80 project knife when it cost at least $260 new.
But again, I wasn't personally speaking about the Takeda, I'm just calling it by name in this post because this is a Takeda thread, I was/am speaking on your original comment that you shouldn't buy a handmade knife if you can't change geometries, basically inferring novice sharpeners shouldn't expect top notch performance out of the box and instead should expect a lame project knife.
Just to add a couple thoughts I wasn't clear about...
Yes, with a handmade rustic style blade and really any knife, there is expected upkeep and maintenance and just some touching up to get it where it should be, I think most here understand that, just like in the analogy, where most who buy an M3 understand it's more finicky and demanding then a regular Bimmer, but to beat a dead horse, it doesn't mean knives like these should come out of the box underperforming to the extreme where they're only comparable to a blade at a price point akin to literally a 3rd of it's value or less.
That is all haha.
I'm by no means an expert on knives but I would think there would be some level of consistency even with a completely handmade knife given his expertise.
It also makes me wonder if the people who receive the ones with no issues are the ones made by Takeda himself while the other ones, like my wedgie, was made by an apprentice. It is an awesome cutter though, after it was thinned.
