Tank....you're back professing your love for torx yet in another thread...Sorry, but allen heads last longer than torx. There is nowhere near the amount of support on a shallow torx head compared to a deep allen head, not even close. It all depends on design as well. CRK allen heads are deep (this is where the difference is) torx used on folders are shallow, and quite frankly - garbage. It's a matter of surface area here - that's a fact. When manufacturers start using torx heads as deep as CRK allen heads, then we'll talk.
