The difference between carbon steel vs stainless is the ease of sharpening for me. The rust factor is something that can be easily remedied using vaseline or silicone spray..... i have a tough time getting stainless steel broadheads as sharp as i'd like them to be.
I have knives like that too, and prefer the ease of bringing that edge right back to surgically sharp with a few strokes on a stone. Oh sure... the blades aren't as purdy as those shinny stainless blades, but they are more practical.
Hey Pat.... your post came in before mine... Great minds, and all that eh?
