In this case, Thomas Lie-Nielsen took the balance and feel of the 750, but he made the blade using tough cryogenically treated A2 steel instead of carbon steel. He also replaced the ugly red painted oak (I think it’s oak) handle with a finely turned and finished American hornbeam version. Manufacturing Details Quite simply, the chisel is a quality tool in every way. The edges on the side of the blade are precisely ground close to the face, which allows you to pare out waste between dovetail tails without dinging your joint. The face of the blade (it’s the unbeveled side, sometimes called the “back”) is ground and polished flat, a remarkable fact I observed on all seven Lie-Nielsen chisels I set up. Unlike handplane irons, chisels must have a completely flat face to do good work. If the face is convex or concave the tool will wander off course as you pare and chop. And learning to compensate for the problem is impossible because the condition of the face varies from tool to tool. In my job at Popular Woodworking, and after many years of working wood, I’ve set up hundreds of edge tools, both new and vintage. And until I set up the Lie-Nielsen chisels, I could count the number of truly flat faces I’ve encountered on one hand. I now have to use two hands. That alone is a remarkable achievement. Also worth noting is that these chisels are made in true imperial widths and not the metric equivalents – which are common on Japanese and European tools. And the widths are precisely ground. All five chisels were within .001” of their stated widths, something you rarely find among sloppily made consumer brands. The American hornbeam handle is tougher than you might expect, too. Though bevel-edge chisels are not generally struck, these tools can take their licks. In one extreme example, I used the 3/8” model to chop several 1”-deep mortises, and I wailed on the handle like it was a pigsticker mortising chisel. No matter how much force I used, I could only dimple the butt of the handle, not split it. In fact, Lie-Nielsen says his employees tested the handles by striking them with a framing hammer and also could not split them. Score one for American hornbeam. Edge Durability Whenever people go chisel shopping, they want to know about edge durability. I would argue that handle ergonomics are actually more important, however, as long as the blade is tougher than tinfoil.
To stress the edges, we pounded the chisels into a piece of redheart, an exotic wood that is particularly unkind to edge tools. We struck each tool using a brass mallet dropped from the same height. After every 20 whacks, we examined the edges under a 30x jewelers’ loupe, pared cherry end grain with the tool and observed the finish left by the edge and the amount of effort required to make this difficult paring cut. In all, each tool received more than 120 whacks. We then repeated the entire test to confirm our results. This combination of paring and chopping also pointed out the merits and defects of the handles of all the tools.
