I have dealt with BM directly for at least 7 years on actually hundreds of knives. If you ever see a totally wasted BM, with zero paint on the frame and a broken blade, for under $50, buy it, better yet if the knife you see is a discontinued model, here's why. BM will replace any broken or damaged discont. knife for a flat $35 plus shipping . example I sent in several 710's wrecked and got various knives of my choice for $35.00. ON auto's they will keep your knife unless you can produce a militery or police file #. unless you can do that, never send in an auto. As to the spring being weak, which i disagree with. it is impossible for bm to know how the spring broke, this repair would have been free > shipping had the knife never be opened, BM trains the very best for their warrently dept, when a knife is sent to that dept, you rec. a better knife than is mass produced. the attention to detail is unreal and the latest and greatest parts are used. BM will also allow you during this timne to select or upgrade your blades for what was $ 12 for years to I think $15 now. so if you have 440c and they make a blade in s30v you can upgrade to s30v for 15.00. If you call direct and act nice, they never charge the assb. fee, only the 15. It is also a good time to make custom knives, many blades will fit other knives, so you could end up with a tanto 1/2 serr. in a knife that you will never see in a store. If you are into designer names, I have asked, and never got a no, to have the actual designer sign the blades, they freely do that, if they are there and working. many options, never send in your box,
