Well both failed, the SP-51 and the 420 HC (OKC's special type I believe), splitting on that frozen knotty jack pine log. My point was even the Woodsman blade was sharp, edge was fine and was perfectly straight. SP-51 was fine as usual.
For heavy use blade I prefer saber grinds. The SP-51 or SP-53 is my primary in the woods blade. The 5160 knives what I put them through some times like bending it as it goes back made some people cringe.
But being a copied SP-50 that is FULL TANG, the Woodsman is a good general purpose knife with no coating, the 5160 or the 420 HC. The FFG is some thing that needs some lighter duties to me. For food processing, to light to medium duty the Woodsman I use as it is a non coated knife. I like the 420 HC Woodsman for water borne misadventures. I usually athletic tape the handles on it though, the handle gets slippery when wet.
As can be seen as the SP-50/Woodsman Design is a just a large kitchen butcher knife descendant. The 420 HC gets used for large critter cutting season in my evil step mother's hands (Hey its TRADITION to call them evil!) and is her favorite butcher knife. She stole it from my dad, as I gave it to him for a birth day present, and keeps it locked in her office so a few of her daughters don't steal the steel. She "Borrowed" the first one when I gave one to my little brother who also used it for cooking and field use, when he moved out he stole it back. I gave them the Woodsman not to get rid of them, but I knew they could get more use out of them, so I gave them the ones I normally got as back ups. I still got my 5160 and 420 HC ones though, as they get use during large critter cutting season.
