i have a buck 110 that i have only carried maybe 3 times - today i noticed that when it is closed, the blade rocks back and forth in the handle (closed blade play, i guess you could call it)- i have another one that does not do this - and i looked at a friend's 110 (older than mine ) and his also does this , but not as bad - when mine is open it has just a hair of blade play , nothing major ( so does my friend's) - but my other one does not - is this normal for 110's ? should i be worried and send it in to buck ? - or is this common ? - i have had 110's and 112's in the past and never noticed this, but i used to not really care or look too close at things like this- thanks for any help or comments - marc
