Moxon vises are pretty popular nowadays, and quite useful. Most bench vises are somewhat limited in their ability to clamp a workpiece vertically, hence the Moxon. I used hardware for mine from Tools For Working Wood in Brooklyn. The instructions suggest a thin chop that is slightly thicker in the center as opposed to many with a thick more stable chop. As the thin sloped chop clamps on something, it conforms to match the object. I chose to follow the suggestion, and it works beautifully. The "ears" on the sides allow the vise to be clamped to a bench top like here, or with holdfasts. I added a small clamping shelf on the back to assist with dovetail layout. The vise is here pictured on my somewhat busy bench at work. I lined the inside of the chop with cork, adhered with hide glue. In theory, this mitigates marring of a workpiece and increases the friction component of the vise's grip, but in practice the cork is weak and gets dinged up and scraped away during minor use. Perhaps one day I will replace the cork with leather.
