I've got these since a few years and haven't fount myself wanting anything else since.
- Glock Bayonet, available cheap and plentiful. I use this on Camping Trips etc, really useful, versatile and light. Used for everything including when I forgot to bring my fork & knife for the barbecue
- Unknown Leatherman I to as a Gift, really great as every-day Tool. Great selection of Tools and compact/light so it doesn't stick out in an Office environment. Very useful!
-SOG Flash, super-handy mini folding blade. Can be brought out super fast, do it job (Opening Packages
) and disappear again without a trace.
