I really wish BM would do an XL version of the 425... I had this Sprint, and the s90v was incredible. I think it tested 63.2. Ultimately though, it was the final nail in the coffin for me trying to force myself to tolerate the compression lock. The way you have to hold a knife to unlock the compression lock just felt extra stupid in this model. My all time most used folder is a custom thats kinda like a cross between this and the Mamba.
I never got the chance to try the BM 425, but I like the looks of it. Ah, yeah, I know what you mean about having to almost pinch the knife to close with the compression lock. I think may have gotten used to it over the years 😂. Your all time folder most used sounds pretty dope, what is it?
