My older GSO-4.1 was thicker but still ~0.030" and 15-dps.
My GSO-5.1 is only
0.020" at the edge-shoulder, and that shoulder isn't wide! From apex to shoulder is ~14+dps, with the primary grind at 5-dps as usual. The cutting ability is quite high.
I also own a rodent solution, HRLM, RatManDu, and Rodent 9 all from the Swamp, and a SYKCO 511 and Busse Hog Muk as well. The only Bussekin that came to me with comparable geometry was the Muk - 0.020" at the shoulder, ~15-dps. All the others required
significant adjustment to bring them down to 15-dps, and all are thicker at the shoulder, even the Rodent Solution. Once you bring them down, they are made of strong and tough steel :thumbup: But the coating drags substantially on deep cuts through cardboard or splitting wood.
If you are comparing the cost of each, the Rats and Dogs are cheaper by ~$50 on average, but they usually only come in SR101 steel, are naked (no sheath), and may require significant edge adjustment to get them cutting like a GSO from Survive! knives. So when you add in the price of a sheath as nice as Kiah provides for Guy's knives, + time/tools to adjust the edge, + the downside of a good thick coating, you may find that the GSO knives are actually cheaper and ready to go the moment they arrive!
All that said, I really like the designs of some of those Bussekin, which is probably why I own more of them than any other company

The handles are generally
very comfortable, and I am not afraid to use them hard.
But Guy has a good thing going here :thumbup: I am currently waiting for my Necker II.
