How come?
How do they last 20% longer than Zenith blades? Did you have identical chippers, chipping the same amount, of the same material at the same job site? Are they made of some type of steel we never heard of? Are they made of carbide? Well you want to sell me your hard edge blades you gotta try harder than that. I need specs, prices, something more than the 20%, and you got to prove it, not just tell me. A web site would be nice or a catalog. I find it hard to justify one blade being better than the other. One day I might be doing a large take down, in a pristine yard, with not an ounce of gravel of rocks around, with a concrete street. The next day might be a large trim job, with a gravel driveway or were the street and the drive way meet, with busted up black top. Rocks and stones reek havoc on your blades so does the species of wood you chip. One day I might chip nothing but ash, locust, or oak, very hard stuff. The next might be white pine, poplar, or bass wood, very soft stuff. Come on man you gotta sell harder than that. I'm happy with Zenith, there friendly, knowledgeable, and my blades are in my hands usually with in 1-2 days, and I feel there pricing is very competitive.
