Typical Benchmade quality and design, but small
Tiny! This is a "little gem" of a knife, but the emphasis is on "little." Great materials and blade design, but truth be told I'd like the handle a little longer so I could get four fingers on it. I gave it to my soldier son-in-law, since he can always use a backup knife to tuck away in his gear.
Stellar little knife!
Just picked this one up to join my 533BK-1 Mini Bugout. Such an ergonomic feel in the hand. For reference, I have skinny fingers but wear M/L size gloves. Easily three fingers on the handle, thumb on the spine. Can’t wait to put this sucker to use in the mountains or even opening up Amazon packages.
2nd type of cool
I had my eye on an Osborne mini but this one is just 2nd type of cool.
