Overview
The JRZ Cobra Black Steel Runners offer absolutely incredible performance and durability thanks to a number of factors. The first is that JRZ manufactures their steel with accurate precision on each and every single one of their runners, ensuring players have a consistent 10 ft. neutral pitch radius and a premium quality product.
The second factor is the Diamond-Like Coating (DLC) blade finish, which provides resilient strength against nicks, chips, corrosion, and scratches. This coating also helps to hold an edge longer and even improves glide so that players can retain more energy shift after shift.
JRZ also designed added height into their blades, even including added steel in both the toe and heel. For players who profile their runners throughout the season or sharpen frequently, this added height throughout the blade ensures they'll have more lifespan over traditional standard runners.
