i got squirt...size is small.
but weight u will feel as its 57gms, even tho u may think its light, all those grams add up especially if u add in keys, led etc.
compare to something lighter like the SAK 58mm classic which is only 21gms.

uhh ok.
1st say concerned about weight, now not.
and obviously it is small, needless to say its one of. Leatherman's smallest tool and also much smaller than wave.
so in that sense, i dont see what else is there to be concerned about.

I have gotten to love the smell of tuf glide. and lithium batteries.

we are actually having this discussion on the cutting edge facebook now,
for lubrication
tuf glide, militec, singer oil, benchmade blue lube, victorinox oil, and a really good one is if you have the fishing lube. daiwa oil that sort of thing
for protection
tuf glide, militec, singer oil, vaseline

my personal preference is fishing reel lube. and tuf glide as corrosion resistance.
