Thread: question about my wade & butcher

the blade has "extra hollow ground" stamped on it.

haha i know this is kind of a weird-ass question but what does that mean? does that mean the blade isnt fully hollow, but its not just 1/2 hollow bc its extra hallow?

It supposedly means has been hollowed an extra amount - an extra hollow is usually very thinly ground

Extra-hollow (aka "singing razor") means even more of the blade is thin than on a full-hollow razor.

I'm a bit confused about the definition of full hollow, the only formal definition I've seen says they should have a "belly" (widening part way down the blade) but I have never seen anything like that on a razor.

Here's an old Henry Althoff razor with a belly. The photo is not great and the Althoff is not the most obvious example, but maybe it will help. It is faint but if you look closely you can see how the edge extends a bit beyond the belly before the bevel appears

According to this page, full hollow and extra-hollow are the same thing.

Consider the source.

Here I read the same (full=extra).

A singing blade is an extra hollow ground blade with the blade between the belly and the spine being ground very thin. They will give a "zing" sound when they are stropped and sometimes while shaving. This takes a very high quality of steel to make these. Full hollow is not ground as thin as the singing. Singing blades are the thinest and full wedges are the thickest.

I disagree that extra hollow is the same as full hollow. "Extra" is by comparison to other razors, and as trends show, Sheffield has (or had) a different idea of what constitutes hollow than the rest of the razor making world. In fact, an "Extra Hollow Ground" W&B (the shoulderless one) arrive here today. I would call it a 3/4 hollow blade. By comparison, Sheffield "Hollow Ground" blades (which are often "Celebrated") tend to be quarter hollows.) So, in the scheme of things, extra hollows are indeed extra hollow, but are not full hollows.
