This is an interesting subject, as my EDC got a good use this pm!! Our new animal sitter locked the door in the garage, that leads to the house, that we NEVER lock and a few other things. We ALWAYS, and only comr through the garage!! We were locked out of our house tonight!! Well, I thought I would go see if the bedroom sliding glass door was open, and it was!! BUT, there is a wood slat thing, that has a sliding lock at the top!! Well, we had to cut the slats closets to the lock, so we could get int the house tonight!! My Spyderco Spin and Atwood Solar Arc got a work out tonight!! And my Spin IS a very tough little knife!!! I AM impressed!!
