Glock is just fine for getting mud out of tank tracks. Its a disposable light weight battle blade, which doesn't take up much room on ones webbing order.
They are tough, though a bit soft and the edge doesn't hold long so requires regular maintenance. They will give you feedback as they bend before breaking, rather than harder blades that just snap without warning. They are cheap and should be $30... I buy in bulk. I throw them for sport so destroy one a year.
Soft tip from throwing into hard wood. I generally grind them off as I do the edge once beaten up:
The handles do deteriorate if left out in the sun for years. From throwing they do eventually break up though for small dings they can be melted back in.
They are a perfectly OK knife, but nothing fantastic. I would prefer the JP Peltonen Sissipuukko or a Terava 140 for a modest field combat/utility knife. To me a Combat knife is not just a personal tool but a team tool. Its for beating on and best if it survives a beating than snaps. Don't cry if its destroyed from digging rocks and roots out of your trench. The sharp edge is your Spyderco folder or multitool; your combat knife is for poking and prying things. Plus ten miles into a forced march is it light weight enough not to be adding to your grief?
For the home front then get something more refined.
