Review on HFS Steel Parallel Parallels Hardened: Ultimate Precision and Durability for Industrial Applications by Greg Greiner

I needed a vise parallel set, strong construction to withstand milling machine work without paying a high price for a 'brand'. name' - and that's it. I didn't buy this set to use gauge blocks, I bought them to be parallel and they adjust that score to within a few tenths. And stupid me, I didn't even think about the case when they came, although mine opens and closes perfectly with a latch, and in fact I cut off the lid, not wanting to access the parallels faster! I did the unpacking and cleaning without a chisel and didn't even break a nail.
