My son loves these blades. He has tried others, but prefers Tydan diamond edge. This is his 3rd set. He’s been using the custom profile and hollow that was suggested to him by the Tydan staff for a while now and has seen improvement in edges and flat out speed. We definitely recommend these blades!
These replaced the stock speed blades in my new CCM Ribcores which I just couldn't quite adjust to the profile of. I got these with a quad zero profile and immediately felt comfortable on them. I've played a handful of games and the edges still seem brand new. Also delivered in two days from Ontario to Seattle, which was a welcomed surprise. I will likely purchase a second set.
