I recently returned a Buck Mayo TNT knife that had several functional and cosmetic issues. Buck very quickly sent a replacement that also has some issues. The frame lock is very weak. When closed the blade has so little pressure from the frame lock that you can lift the knife by the blade and the handle falls open. Too dangerous to use as a pocket carry. I have a Waimea that locks firm and the blade has a nice bump as it closes into the handle. The blade on the TNT also has lots of sideplay when opened. The Waimea locks very firm. I bought the original knife from Ira Woods and they told me to return it to Buck. I've bought well over $1000 worth of Buck knives this past year and all have been dang near perfect in every way. These two TNTs have been very surprising to me. Does anyone else have a TNT that falls open when you pick it up by the blade? Is that just a design feature? My 271 Alpha Dorado is very tight in the handle. I got the TNT to carry. I was expecting it to be similar to my Waimea in function. But I can't carry a knife like this. If this is the way the TNTs are made I'll sell it on ebay and take my lumps but I need to know before I do that so I don't sell a dangerous or flawed knife on ebay. If TNT owners could chime in I would appreciate it. Thanks! Bilrus61
