Lets see if I can't help feelings rather than stir up troubles.
First the 307 is discontinued, but Buck will fix it, BUT it was involved with the closing of the Camillus factory. Parts left over were assembled at the very end and sold. Some parts and old boxes were sold and former employees bought, assembled, and sold them, especially on the bay. So we have several 307 situations that I consider not quite "BUCK" normal. When buying from Whee-bay be sure your seller has a good return policy. Don't buy a 307 or other discontinued 300 model from a 'No returns" policy seller. Especially ones that look brand new.
I can't address any personal knowledge on the let down of quality out of the factory. I don't buy many new knives, I maybe have gotten less than two dozen since the factory moved. I have had a couple of imperfections, one I fixed myself (Vantage blade) and lived with others. They are afterall good but not costly knives (300s). If you buy them in a bubble pack from the 'mart' be sure to carefully study them before checking out. The two or three I bought at Branson and SMKWs were all top notch out of a box into the hand before money was exchanged. When I am in Idaho next summer at the BCCI celebration at the factory, I will quiz folks on the high spey blades, especially in the 301 model. The 303 seems to have less of a problem with this.
Buck folks on this forum - I know Buck employees read here pretty frequently. I doubt they feel they can openly comment on some of our complaints. I do know that things tightened up during last few years with the economy shifts and that Joe Houser stays running. I personally do not get all my emails replied to and when I do it is several days or even a week or two later. So at least give him a few days before thinking you are not getting a email back. They are also hunters and the fall is a tough time to get instant particular person service....know what I mean.
I have read the over in the Buck forum where Razorblades has had some bad experiences and I hope someone from Buck will comment to him. It is tougher to deal with some of those issues in Canada. And its tougher living in the sticks. I still would trade the the sticks for the tougher dealings given the choice......
In the end I would like Buck to be perfect but they are not. I can't gripe too loud because I get unfancy $35.00 stockmen which are ment to be in the pockets of farmers, ranchers, woodworkers, carpet layers, dozer drivers etc. Buck says if they foul up we will fix situation. I want them to be perfect but will stretch perfect a little because of the price. This is my opinion and I am still appreciative and understanding of Razors and others situations and desires. When they get to the point they won't fix it in the end, I would like to hear about it......300Bucks
