Thread: Laser engraving on a Wosty I-XL?

I have a Wostenholm I-XL that I am going to restore and rescale as a family heirloom. I am planning on having my surname laser engraved on the blade.

Will laser engraving hurt the temper or any other aspect of the razor?

Thanks in advance,
Marc

Edit: At what point in the restoration should the engraving be done? I was thinking right before I started the working with the 2000 grit paper but this is totally a guess based on zero experience.

Ugh!

Please don't call laser burning a design in metal engraving. Calling what a laser does engraving is like calling a wore out trailer trash crack whore a beauty queen.

Let me put it another way. Its like calling a Mach5 cartridge razor a straight razor. It just aint right.

To answer your question, I would suggest finding someone who does that and ask about the heat generated and how far it will dissipate. As long as the heat doesn't dissipate to the edge of the razor it shouldn't hurt the temper.
My only concern would be, will it generate enough heat in a localized area to cause any warpage due to changing the stresses in the steel. I honestly don't know the answer to that. You will need to find someone who has a bit of experience and ask them.

Laser etching should not hurt the temper, as long as you are not etching right up to the edge of course.
From what I understood, the laser pulse is energetic enough to instantly vaporize the metal, and short enough that it doesn't sink heat into the blade.

Of course you might want to try this first with a dud razor.

Ray, my sincerest apologies. I meant no offense to those that do engraving. I was only referring to it as the place that I will be going to does. Thank you for educating me in the proper terminology.

Bruno, great idea about using a dud razor first. I might have one or two sitting around that would be perfect for that.

No harm no foul, no apologies needed. When I see that term "laser engraving" used, I try to point out that it really isn't engraving. I know it is pushing back against years of marketing but I still think its important to make people think about it.

Lasers were introduced in this market as a "cheap alternative" just like the pantographs were decades ago. Because both these marking methods were marketed as engraving for so many years a lot of people don't even know what real engraving is anymore. Its very similar to the relationship between cartridge razors and straight razors. One is a cheap way to get the job done. The other has a little more depth and art to it.

I'm never really offended when folks use the terms but I will always use the opportunity to push back against years of what I consider false advertising.

I would personally have it hand engraved. It has much more personality especially if done by a true artist.

I'm not an expert but from all the data I have collected the most common and also more affordable laser engravers on the market use a CO2 laser which enables you to mark steel only with a special metal marking spray. To engrave in the steel you need a laser that uses a YAG laser which has a much shorter wavelength (1.064 microns) compared to CO2.
