I have 5 vices that were much more expensive than these. I use them for electronics and wood/metal work. I started picking locks (picking locks for fun, not for profit/crime). I had a much nicer vise that I used, but it didn't lean into the ball like this one, so my hands cramped. Since I like to sit and watch TV when I'm breaking in, I didn't want those prettier vises tied away from my workshop. That's where these vices come in. They're super adjustable and easily get custom angles that help with awkward slumps. The vise is very light for a vise (feels like aluminum and plastic). Because it's quite heavy, you could probably draw little figures in it without attaching it to a piece of wood or something. Since I clamp heavy locks and apply force to them, I absolutely had to attach them to the base. I made sure to put the vise off center as it will hold what you are working on to the side. I chose a metal surgical tray with a notch (pointing up) down the middle. Mounting holes are well drilled. If you are mounting to a block of wood you will need to put a bolt/screw through the top. I installed it on a surgical tray, so I feed the screws from below. The screws I used have huge flat smooth heads that act like legs. Yes, I have to look at comparatively ugly nuts when using a vise, but pan head screws don't scratch the table surface like nuts. Minus 1 star because: you mention fine/coarse adjustment, but it's the same knob, same adjustment. Yes, you can hold the wing nut-like part of the handle, but it's attached to the bulbous part of the handle. So you can only open / close the jaws well. Too good. I only switch between locks of the same size every few days and it's annoying. I can't imagine swapping between different sized work pieces in one day. They sell a speed controller that's bigger for it, but I don't reward bad business decisions. By the way, I knew about the pen, but still! Eventually I might just drill a hole the diameter of the grip and stick a thin metal rod in to use my own speed grip lever. There is a wide Panavise on the Internet. A jaw mod you can make to make this thing double the size for about $7. Panavise has three vices: the cheapest with a medium jaw opening; more expensive, more powerful, but opens LESS wide; and the most expensive, which is as simple as this one but opens twice as wide. The vise can cost over $1,000 and is very profitable for me. It's very cheap and super adjustable. If you want a wider jaw opening: check out the $7 mod and see if you can do it, or pay three times as much for the pricey Panavise. Your middle vise is similar to an anvil vise. found it at someone's flea market for five bucks. Only it's more expensive, smaller and lighter, and the jaws don't open wide. It's a little strange, but many tools are specialized, so someone probably likes them for some reason. Panavise also has circuit board holders. This is a great vise as long as you don't have to clamp things of different sizes in it all day. The extra fine thread pitch makes opening/closing the vise tiring. If you stuff stuff in there and work on it all day, this might be the cheap vise for you. For fun crackers, that's probably 5 stars (super cheap and super adjustable). actually be unusable with a fine thread / non-existing coarse adjustment. Love it and would buy one as a gift for a locksmith (or myself if I needed a different picking vise).
