Welcome to the forums! I have an SnG but it is the same as the SMF just slightly smaller. I use a PSD products spanner tool. It has the appropriate size torx head in the middle of it to adjust/remove the body screws and pocket clip screws which is a nice feature to have. This one here: http://www.monkeyedge.com/PSD_Produc...0002-me081.htm
Mine has not had ANY play and is still rock-solid. I have tried it with gloves and yes, it does work. Maybe not with very thick gloves but it should be fine with a pair of Mechanix. A lanyard helps extract it from your pocket but it is do-able without one while wearing a glove. I love mine and the only issue is that my blade is VERY slightly off center but it doesn't bug me or affect functionality. I say go for it and if you have any issues, Strider will correct them no questions asked even if you break it.
