Recently, I purchased a 7" Groz Rapid Action Vise. After installing it, I noticed that the two clamping surfaces do not come together flush, these surfaces are slightly toed so that they meet along the top edge,leaving about a 3/16" gap at the bottom. My first thought was some sort of manufacturing defect, but after taking it back to Woodcrafters, who were very helpful, I discovered that all Groz models do the same. Groz vises are made to toe-in along the top for greater clamping pressure. It seems to me, however, that this condition creates a greater possibility of damaging materials in the vise. It would seem preferable to have two flush surfaces that can distribute the clamping force across a larger surface rather than concetrate that force along the top edge. That said, I do plan to put hardwood blocks along both surfaces, but I still have doubts that the toed surfaces are a good design feature.
