I use American Lock Government (model A5200GLNKA). The one time I had to help someone cut one of these (he forgot the keys to the case when we where on a trip) we actually ended up cutting the pelican case becausr it was easier. Broke a set of bolt cutters, the hand saw broke and only got about 1/16" deep, and the sawzall was taking way too long. So we just cut the case to get it open.
