GREAT BLADE

Would Recommend

I work in the Trades amd this blade is a GREAT tool! It has taken some serious abuse and has remained sharp! I also use it for the great outdoors. I just replaced my old one with this new one. I highly recommend this Blade/Tool

Awful scabbard ruins it

Would Not Recommend

bought this having been a long time Klein fan, Overall though the knife isn't bad. The scabbard however, is awful, the loop is so large it dangles even on 1.75 belts. The cheap canvas tears when you look at it sideways and worst of all? the Velcro used to hold the blade stops working in a month.
