Since we're getting a snow environment in SPECTRE , I wouldn't mind if Bond used a winter coat with a parachute incorporated, for a quick escape on the top of a mountain or some high place.
That's a good one. I've also a considered a winter coat that Bond could use. From one sleeve or the other, it fires a piton as an anchor with a line that allows him to "free run" or simply just descend from a high peak (or perhaps a structure) to safety. DAD had something similar with Jinx's device.
Some stunt chaps I know have done a few crazy things (and lived) with 300 lbs. fishing line just to see if it could work.
If we went back to a pen gag, rather than a laser thing, how about a good old school cutting torch. Hot blue/gold high temperature style. You know, just to do something silly like cut through bars or iron plates. No acid or lasers, just simple.
I just recently read (again) Gardner's first "Licence Renewed" and enjoyed it again. Bond's smoking is addressed and it also features as another item(s) that Bond utilizes. The lighter charged with halothane and the bugs hidden in cigarettes.
I also like the idea of a laser/cutting beam used in the guise of an E-Cigarette.
As to the more lethal elements, much like the pen guns, an E-Cig could easily fire a .22 which did a lot of damage in the cold war.
I've been digging through a few of my "old school" notes on gadgets.
