StatGear SuperVizor XT Auto Emergency Rescue Escape Tool - Seatbelt Cutter & Window Glass Breaker Hammer Survival - Mounts Right to Your Sun-Visor! (2 Pack, GLOW)

After a lot of searching and research I purchased this for a Westfield fitted with 3inch Schroth harnesses and a full cage - access in and out is already challenging at the best of times! In the event of an accident and a jammed release buckle the seats grip so tightly the only way to wriggle out would be to cut the 3 inch wide straps on the seatbelt.There is somewhat limited info on emergency tools online so I hope this extended review helps others in their purchasing.I did consider the more expensive leatherman LT125 or Gul S13. The Gul looked well made but lacked a handle and the leatherman was, I felt, too bulky for a small vehicle like a caterham or Westfield. I wanted a well made but compact emergency tool which I could fasten under the dash for use in the event of an accident.This XT is a good size, not too compact that you can’t get gloved fingers through but not too bulky that it would be difficult to store or mount even in a small track car like a Westfield, caterham, atom, bac mono etc. The steel extends all the way through the handle which is overlaid with a tactile plastic so there is no risk you will pull the handle off in operation - and was why I went with this rather than some other cheaper options on Amazon.Window punch is labelled stainless on packaging. It is riveted/ pinned to the frame and sits in a notch so it cannot rotate in operation.Packaging says frame is 440 stainless and it is magnetic which suggests a martensitic stainless like a 440. The punch is also magnetic (conforming packaging “stainless” and not carbide).At first I thought the positioning of the glass breaker was badly designed because when held point up the point is not axial to your hand and if you hit glass you are not hitting it straight with the point. But turning the XT around and holding it like a combat knife with the point down, the point is then directly under the hand. Bringing the arm down in a stabbing motion on a window holding the XT would, I’m sure, be very effective.The good:Stainless frame extends all the way through the handle so no chance of handle breaking or coming detached under extreme force.Sharp hook and steel measures 2.4mm thick on the frame. Robust, razor sharp and should cut through even the thickest straps and harnesses.Decent glass breaker (not needed on the Westfield but could be a lifesaver if I come across a RTA) and glass breaker is securely riveted with a recess notch to prevent it rotating under load.The not so good:The elastic on the back of the pouch is the only way to easily mount it (for a visor it would be adequate) but it would be good if it had a dedicated robust webbing loop to zip tie it somewhere. I’d be worried in the violence of a crash it breaks free with just elastic to restrain it. I will zip tie it on the flap to secure it in place.Packaging has generic images which suggest glass breaker is held point up, to be effective the unit is designed to be held point down for breaking glass. Documentation in general is non existent on packaging and, given the nature of this product it could benefit from some detailed simple instructions on packaging since the first time you use this product is probably going to be in an emergency.In summary a decently designed and well made bit of kit which I hope I never need to use - but is good to know is there should it be required.Recommend.
