Modified Spyderco Endura12/24/2024 ByMike K. I have purchased several Knives Plus modified Spyderco's - about half with regrind blades, all with the acid stonewash treatment. All have been extremely well done, and the Endura is no exception. I opted for the black hardware this time (have done the bronze color ones before - both are great). The knife has to be fully disassembled to do the acid wash finish, and they all have come to me functioning well and as sharp as you would expect from the factory. If you're thinking about purchasing a modified knife from Knives Plus, there's no downside to it that I have ever seen. I highly recommend the mods they have done. Their blade engraving, if you're considering that, is first class also.
