I've used the Infinity Combomax (010-150), 60T Hi-ATB (010-060), 24T TK ripper (010-124), former Infinity General (010-040), and the Dadonator, all with the Nickel coating....all great blades. The Combomax is the best of the 50T blades I've used to date, and is extremely easy to get good results with (I loaned it to a good friend who I gave a Forrest WWII to as gift, and he won't give the Combomax back!
). The Super General 010-044 with the PTFE coating is the cleanest cutting 40T general purpose blade I've used to date. The Dadonator is the cleanest cutting dado set I've used to date. The Nickel coating works very well and keeps the blades from corroding....those with no coating definitely begin to show some "weathering" after a while.
In a nutshell, I've used several Forrest, several Freud, several CMT, several Leitz, several Onsrud, several Tenryu, several DeWalt series 60, several Delta Industrial, Ridge Carbide, Oshlun, Systimatic, Blue Tornado, Amana Tool, DML, and a few others....mostly all really good blades, but no single brand has impressed me more than Infinity overall. A+.
