I'll have to try and post a picture I took when I received it (hard to do here in Iraq), but I had Justin make me just such a thing. It's 5160, about 5/16th inch thick with a chisel tip. It's strictly for all the nasty tasks. I've dug into the sand to dig up and cut field wire, demolished several junk-piled wood benches/chairs, etc. and used it to cut through sandbags to remove some older fighting positions. It's been used pretty hard and is holding up very well. For a custom for your specific needs, you won't find too many out there to get you want you need for a very reasonable price. Do take note that Justin's work is a littel "rough-around-the-edges", but this has zero impact on performance. If you're looking for a user, I fully recommend him.
