I got a preferred knife / light combo for work and hiking.
Work combo (IT office):
Bessey D-BKWH + Thrunite Neutron 2C v3 + SOG VL02-CP.
A Surefire EWP-02-BL pen should also be in the pic, but that is at my work desk right now.
When I get told to unpack 5 huge cardboard boxes, I'm not using a door key for that, which would be my alternative.
Hiking combo:
Gerber "LMF II" 22-01629N + Fenix PD35 2014.
Not the best output from the PD35, not anymore, but i
trust it - it's been with me for years, and it has never failed me.
The LMF II is overkill 99 % of the time - like making a stick for sausages over a bonfire - but should I need to make shelter, I know it can do it.
