The Roughneck Gorilla Brick Bolster is manufactured from drop-forged and heat-treated superior quality chrome vanadium steel to ensure outstanding toughness and long-life performance. The 45° single chamfer cutting edge offers the optimal balance between cutting performance and longevity. Equipped with a patented non-slip guard that securely locks onto the shaft. Eliminates the age-old problem of grips slipping up the shaft during impact. Additionally, the guard can be removed within seconds to improve access in tight areas or to aid flush cutting.
