Specifications: nominal Length: 8-3/4" Cut Length: 1-1/4" Cutting capacity (CR/SS): 24/28 cuts tight left curves, circles and straight. Longest lasting cutting edge blades are hot drop-forged of molybdenum alloy steel and au temper heat-treated. Strongest blades hot drop-forged process uses grain structure of steel to produce maximum strength. Optimum Serrations blades serrated 40 serrations per inch grip material without scarring. Highest quality components grade 8 blade pivot bolt and heavy-duty double-overwind spring are unconditionally ! Compound leverage multiplies handle force to cutting blades by 8: 1 power ratio. Strongest handles high tensile strength steel will not bend from hand pressure and provides most efficient conversion of hand force to cutting power. Comfortable handle grips thick textured neoprene grips comfort user's hand and prevent steel handles from wearing through.
