I have written several articles about CATRA edge retention testing, including: Patreon supporters paid for about 1/3 of the cost making all of this possible. This study alone was about $12k, and there is no way I could have justified spending that much on knife testing by myself. Neto, Tristan, Gareth Chen, Alvise Miotti Bettanini, Henjie Taguinod, ben horridge, Steven, and Ian Miller for becoming Knife Steel Nerds Patreon supporters!
