I like my Milwaukee hacksaw and it’s miniature counterpart, the full size one is easier than others I’ve used to get tension on the blade. The DeWalt full size one is also pretty good. I use them mostly for cutting copper and PVC when I’m too lazy to haul out the hackzall, the mini hacksaw definitely needs a sharp blade, but I find I can then move it from the mini to the full size and put it under tension and it does fine there when not-as-new anymore.
Also not quite the same thing, but I really like my folding sawzall blade holder Milwaukee makes (yes, I bleed red!). I usually have sawzall blades somewhere, so even if I don’t have a hacksaw blade or didn’t bring the hacksaw, I can still cut wood or metal or pipe or just about whatever.
