Bumping this thread, as I saw something today which is pertinent.
I visited a large chain 'warehouse' sportsman's store (

) today, to take another look at a new Buck 301. I'd looked at them some time back, and had been somewhat on the fence about them, at that time. I pointed to the 301 in the display, and the sales associate behind the counter was quick to pull one out of their stock, still in the box; he handed it to me. I was looking it over, at the 3-layers of springs on the back (no liners separating them), and noticing the very, very tight spacing of the blades in the handle. Opened up each blade, one-by-one, then closed them to check the 'snap' (I'd noticed the last time I looked at these, the springs were very light on these). Snap seemed a little better on the first two blades checked. Upon opening and closing the spey blade, I immediately noticed it wouldn't close on it's own, and had to be gently nudged back into the blade well. It was rubbing against the adjacent sheepsfoot blade. I asked the sales associate if he had another in a box, and he did, so he dug that one out. All of it's blades opened/closed as expected; I went ahead and bought this one.
Upon examining the new knife a little closer at home, I noticed even the 'good' one exhibited some very light rub marks on both the sheepsfoot and spey. They are less conspicuous than sometimes seen on Case or other blades, but still recognizable upon closer examination under some decent light. A lot of the difference in seeing them, or not, seems to come down to the finish on the blades. The lower, hollow portions of Buck's sabre-grind blades have an 'as ground' finish very similar to Case's version of the same, and it seems to somewhat diminish or obscure the obvious nature of rub marks that would otherwise stick out like a sore thumb on a high-polished blade (as with Case's tumbled & polished blades).
All of this is just to voice something that I'd thought about earlier, as to whether the 3-spring arrangement guarantees no rub or not. Seems it doesn't; at least if the blades are still so snugly nestled into the handle. It occurred to me that, to some degree, at least a thin liner between each spring will give each blade a tiny bit more wiggle-room. Otherwise, with relatively thick-spined blades arranged in a 3-spring configuration, with no liners separating them, the tolerances necessary to eliminate any rub at all will have to be very, very tight. At the price-point of knives like these (Case & Buck), I wouldn't expect to see that in each and every knife. It was curious to me, that I found an example to point this out, in the very first of two knives I looked at today.
This is why I still don't worry about the 'cosmetic' issues often associated with light blade rub. I still believe, now more than ever, that it's relatively common in patterns like these, and has been for a long time. The one knife I saw today, with a blade that wouldn't quite close on it's own, is a different matter. And it's also why it's always good to get some 'hands-on' time with a prospective purchase beforehand. The Buck 301 I brought home today looks like a good-workin' & useful tool, as it should be. I'm sure I'll be as satisfied with it, as I am with my other stockman patterns from Case, Queen and others.
