    Question Hollowness of razors



    Hi!

    Is there a web page or forum post with explanation (preferably with pictures) what blades with different grinds (like 1/2 hollow, 1/4 hollow) look like? Can someone tell me about this one?





    It's a Heljestrand no.23 I just bought from an online auction site.

    Excellent website. It did a good job of defining the different grinds. Would someone be able to explain the shaving characteristics of the differnet grinds? This was not mentioned in the link. How do a wedge, 1/4 hollow, 1/2 hollow, full hollow, etc. differ in daily use? Do they feel or shave differently? Thanks in advance.

    P.S. Just to be sure, a 1/2 hollow blade is thiner than a 1/4 hollow, right?

    Most of the difference in feel that I've noticed is in heft and flex. Hollow blades tend to flex more and have a lighter feel in the hand. They are also more likely to nick you if you are not careful. Thicker grinds tend not to flex, and their weight often makes it feel as though they cut through facial hair on their own. They require a bit less finesse to shave with, but as a tradeoff, they can be more difficult to hone (heavier, more steel to remove).

    I have found that framebacks, even if the lower section of the blade is very thin, tend to shave like half or quarter hollows.

    Again, these are my own personal experiences, and are by no means universal.

    Here's another reference on grinds. I believe it was first posted somewhere on SRP, but I have no idea where or by who.

    Holli4pirating, that is a Henckels chart and I don't recall for sure but I think it came from a Henckels catalog early last century

    I also have a 22 Heljestrand, and it appears to be about the same grind as my wapienica. I call it a half hollow and maybe 2 1/2 on the henckels scale

    I understand the chart/website but what's the difference between a full hollow and extra hollow?

    I'm pretty sure an extra hollow is even more hollow than a full hollow. I'm pretty sure the blade becomes thinner closer to the spine.
