I know a few folks that are on various SAR teams that carry Busse blades. I would imagine they would not hesitate to pry a car door open or chop whatever lies in their way when trying to rescue a subject. Often times when we hang out for some trees n quiet, Busses are chopping, being battoned, being thrown, used for digging. You name it really. Bottom line to me, Busse blades will take what you can dish out and if for some freak of nature they fail, they have the best waranty policy.
