That is not how I read it really.I think it's funny that folk recommend the District TF service when Ryan thinks its a joke.
He does the same service for other knives for $45.
He increased the cost to $80 for TF to dissuade customers from tweaking their brand new knives.
He's basically making fun of people who think their TF needs thinning, before even using it, because they read about it on some forum.
He even describes it as a "cosmetic" service.
Read his copy. It's filled with irony.
Due to the overwhelming demand to make perfectly good knives even better, we offer our Teruyasu Fujiwara knife cosmetic regrind service.
For the low price of $80 we will erase all of those nasty things you've read about TF knives on Reddit and other forums.
Dear Fujiwara san, we mean no disrespect to you with this service. Many consumers are misguided by advice on the internet.
When my TF needs thinning it will go to Bernal where they don't use best sanders or charge extra to work on a perfectly good TF...
It would be problematic if, as a reseller, he implied that knives he sold were less than quality. It's basically saying "Hey TF if you read this don't drop this as a vendor". The TFs probably take a little more work to get right since it's not just thinning, it is indeed a regrind as he calls it.
This is backed up by the fact he advertises this service a lot on IG and FB.
Remember that Jiro dropped a vendor for polishing his knife on a jnat.
