Review on Yost FSV-4 Heavy Duty Forged Swivel 360° by Logan Collier

Will damage my second so-called heavy-duty cast iron vise. Yes, I hit him, bent hot steel, and he broke his jaw off the main shaft. The strength of Sast cast iron is approximately 30,000 psi. I think this tempered malleable iron is 130,000 psi and will withstand some abuse. It will replace the 6" Bessey I that I broke. BTW, the reversible YOST 5.5 (855-D20) also replaced the Wilton 11106 I bought that arrived damaged! , but these more expensive YOST vises are better than the so-called high-end name-recognition vises, but still good old cast iron. Don't worry about that unless you bang the vise hard.
