My cold steel voyager tantos have taken more abuse than any other knives I've owned. The large one doubles as a small prying tool and the serrated section eats laminated glass. I've been carrying these for about 7 years now. As for tempored glass and seatbelts, the smith and wesson rescue knife with the spring loaded center punch works great. I have lost count how many windows and seatbelts I have used it on. But we have three interstates and two major railways passing through the district. There are probably better knives out there but my Cold Steels are good sturdy work knives. Steve Wanna kill these ads? We can help!
