My old BK-9 in 0170-6C is a very good chopper. I put a micarta handle on mine. The Beckers are good knives, but not quite as tough as the Scrappers. To answer your question, the BK-9 Combat Bowie will outchop both the Yard Guard and and Yard Hook, as you might expect a 9" blade to do. But the new SOD should give it a run for its money.
