Thread: How Bevel is Affected by Taping

Okay, this may not be news for some. I wanted to know how much the application of a single layer of electrical tape to the spine of a razor you are honing affects the angle of the bevel (as compared to no tape). So I took two measurements on the nine (9) razors I currently own:

1. blade width from the thickest part of the spine(which is what contacts the hone) to the edge
2. thickness of the spine

Then I used the following formula to calculate the theoretical bevel angle (I'm not smart enough to work these computers so I am showing a photo of the formula):

Where (still not smart enough, I insert yet another picture of a picture):

Note: I divided the spine width by two to get the actual bevel angle. Otherwise I would have calculated the included angle of both sides of the blade.

I then ran the calculations as above and added 0.007" (the typical tape thickness or TTT for those that dig abbreviations) to O to calculate the angle (theoretical) with tape.

Here's the data Oh my God I'm so stupid! I have to put in another picture):


Conclusions:

• Yes, taping the spine will affect the geometry of the bevel (but DUH Icedog! we already knew that!)
• The narrower the blade, the more it's bevel will be affected by taping.
• I need more big razors
• I really need to get back to work!

So what do you think about that?
