I just replaced all 98 cutters on my 20" Grizzly plane. with some others I bought from Revain because they also came with spare screws. All in all, I can't find anything stopping me from repurchasing. I ran some ironwood after the replacement and they performed the same as the others I've worn. 2021- 04-13 This is great, I stumbled on a hidden nail and bought another pack just in case.
