Thread: Measure your razor angle !!!!!

Razor: Average Thickness(mm) Length(mm) Angle

Thistle Cut Co. 3.433 12.76 15.44
Henckels 4.783 15.97 17.213
Le Grelot 5.83 18.61 18.02
Winchester 4.046 14.22 16.36
Joe Chandler Damascus 7.366 17.23 24.68
Robert Williams Custom 7.04 21.08 19.224
Joe Chandler Custom 4.987 20.1 14.25

Angles are calculated with the original lengths carried out to more decimal places for increased accuracy.

Interesting project!

EDIT: That 24.68 Degree for my Chandler razor was bothering me, but I checked it again & that's correct. It shaves well too. I don't know what to think about this

Here ya go a thread all about discussing the Mathmatics of this project...

Let's measure razors here OK????

glen it seems your link is dead...

FWIW, I am at work yesterday, today and tomorrow and do work long hours. When I get to it I will measure a bunch of 6/8 razors since that is what the Hart is and it started all of this. I want to compare the vintage 6/8 to the Hart and see if it really is out of the 'correct' range of angle.

And my favorite razor was shaving so swell until I squeezed the edge with the carbide face on my caliper. It was kinda fun: the harder I squeezed the smaller the number got. Who needs a breadknife when you have a caliper? I'll bet that mini C clamp that some call a micrometer would work even better.

RAZOR: spine width - blade width - calculated angle
Jospeh Rodgers wedge: 5,3 - 19,1 - 16,0
Thomas Ibbotson wedge: 5,3 - 18,2 - 16,7
John Sellers wedge: 5,5 - 16,9 - 18,7
Frederick Reynolds wedge: 5 - 15,7 - 18,3
NOS Friodur 7/8 SS full hollow: 6 - 19,4 - 17,8
Jopri n°860 full hollow: 5,9 - 19,3 - 17,6
S. Pearson&co 3/4 hollow: 5,2 - 17,5 - 17,1
Double Arrow 3/4 hollow?: 5,8 - 19,4 - 17,2
SansSouci full hollow: 5,4 - 16,65 - 18,7
Bartmann 504 full hollow: 6,2 - 20 - 17,8

my house razor is
.7240 tall and .1520 thick spine (yes i know its thin)

this is not the blade blank project razor spec this razor was made well before i found the stock for the project
i will have to see what the blade blanks have been coming out to

Spine width and blade width

Marshes & Shepherd wedge .218" .635" moderate hone wear
John Barber wedge .234" .668" moderate hone wear
Wm Greaves & Sons wedge .232" .655" moderate hone wear
Edward Barnes & Sons wedge .225" .636" moderate hone wear
Teer & Webster wedge .235" .765" minimal hone wear
W.Greaves wedge (early stub tail) .158" .630" moderate hone wear
Boker King Cutter hollow .215" .725" minimal hone wear
Boker King Cutter hollow .179" .633" minimal hone wear
Joseph Rodgers & Sons hollow .205" .722" almost no hone wear
John Williams hollow .185" .620" almost no hone wear

All razors honed with one layer of electrical tape.

Vintage J.A. Henkels ................ 4mm x 11.5mm = 19.74 degrees

Buddel Suminagashi Custom .... 5mm x 19mm = 15.00 degrees

TI Le Canadien ........................ 5mm x 17mm = 16.74 degrees

HART Steel (BG) ...................... 5mm x 19mm = 15.00 degrees

Bill Ellis Hybrid ........................ 4.25mm x 16mm = 15.14 degrees


I hone all of these razors (except for the henkel and the TI where I use no tape) with one peice of tape that is 0.2mm thick. This increases the above values by 1.18 degrees.

See now I haven't laughed out loud in a long time over reading something. Bruce, thank you for that. I have a digital caliper and I thought something similar. There's no way that caliper is getting anywhere near any of my razors unless they're butterknife dull 35 degree+ Sheffield wedges.

I've got to say I reread Bruce's quote and I'm still laughing. Of course, I know Bruce so when I read it, in my mind I'm hearing him say it.
