Interesting post on de terms with graphics

Hope not against rules to discuss

Maybe not best metrician tools but:

Great idea for this guy to post. Hopefully he will post here as well. That combined with a database of razor metrics would make for great sticky in service to members

Excellent illustration DanLaw , there is a whole lot more going on in a DE safety razor than I imagined! Now I want to see a similar illustration for a slant razor.

Just to be clear, this is not my work. A member of B&B did this

You should post on the B&B thread. He will probably follow up. My guess is that the gaps prob dont change but rather the angle og attack changes throughout the stroke akin to j hooking. No research to back this nor a lot of thought truth told

Nope, I'd have to sign up to post and I've got enough on my hands with one forum. A take aaa from that illustration is with so many variables, its no surprise that different razors can shave so differently even when they look the same to the naked eye.

It's neat & all that, but it's no real indicator of how well the razor will shave for you. Razors are as personal as blades in that you have to try it to see if it's for you. There's a Helluva difference between looking at the brochure on the showroom floor and sitting behind the wheel going down the road.

Well said.

One could argue that numbers speak loudly and directionally if one takes the time to learn what they mean. While not at that level of knowledge yet regarding DE geometry, getting there with straight edges and absolutely 100% there regarding autos and bikes. No auto nor bike surprises me these days.

With proper training and experience one can tell a lot, almost everything, from the numbers and mechanical drawings; the actual use will only reveal the very last few percent.

Did someone mention B&B?
People still go there?
By the way, I gap my blades every 50,000 miles or 6 months, whichever occurs first.

Wasn’t trying to be smarta$$ just state that even bad scientific methodology is better than random guessing or literally trying blindly until something works. The unscientific approach leads to buying and reselling lots of hardware which is frustrating and expensive.

I am not involved in this particular endeavour but think it has merit. Once physical parametre database is in place then a mapping of what characteristics suit skin and beard types can guide people to an array of razors that work best.

Shaving software (soaps&c) may not be a good match for this type of mapping but having it for hardware like razors would have saved me a lot of time, pain, mistakes and money.
