Great knife , just like it's brother , the Rat 1. Awesome value in a tough folder. A little heavier in the pocket than some others, but not too bad.
I have the rounded handle model Utilitac, which feels better in the hand than the squarish one. I love the Rat 1 and Utilitac for EDC carry , and if I did happen to lose it I'm not out a lot of money and it's commonly available for replacement.
Ontario's Aus-8 seems to be well heat treated ( no major edge deformations with regular use so far whittling , cardboard , plastic, bush use , etc. and sharpens up easily.
