If this works for a knife, can it work for a SR? http://digg.com/video/the-best-knife-sharpener-is-a-car?utm_source=digg&utm_medium=email And has anyone ever tried this? Seems a bit over-the-top.
The next time I'm shaving in the garage or in the Serengeti, I'll have to give this a shot! BTW: what works on knives for sharpening rarely transfers to the sharpening of SRs.
looks like a good way to break or crack a blade. a knife is a knife a razor is a razor. would you open a letter with the razor you shave with?
The edge of a car window would be an edge dresser at best and I've used it at the deer lease many times. It works for a knife quite well. A razor? That'd be dumb.
I'll try just about anything a couple of times. I wouldn't do this with a straight razor. I'm real happy with the sharpening results I'm getting, no need to try a car window.
I imagine the car window will be between 250-1000 grid. A finishing hone is 10,000-12,000. Any edge you could put on with a car windshield edge would need major repair. Long arm hair is not facial stubble and you can shave arm hair with almost anything reasonably sharp.
I've used the edge of a car window like that for sharpening a knife and it definitely will work. How ever sharpening a straight razor to use on your face is a different matter. Think of all the various DE blades you can use to shave with, that are literally "razor sharp" and are made specifically to shave with, that don't work well if at all depending on the persons skin, beard, technique or prep. That said you could try this method of sharpening and it may actually work for you. But the odds on bet is that you'll get a "TERRIBLE" shave, "HORRIBLE"" irritation, wind up donating a little blood and "ABSOLUTELY" worst of all ruin the edge of a perfectly shave sharp straight razor. As @Omaney said if you need to touch up a knife edge to gut a deer or rabbit, cut some cordage or whittle some wood into a stake and all you have available is the edge of a car window then use it. That car window trick will work fine, you can also use a piece of smooth concrete the same way, although IMO a good sharpening steel will work better than either and is "ALOT" more portable.. For your straight razor use a proper hone and a good strop..
I had NO intention of ever subjecting my straights to this; I just thought it would be an interesting topic since I had never heard of doing this. I do, however, plan on trying it on a knife or two. Frankly, I'm more concerned about damaging my car window!
I really hope no one tries this. Knives and razors are different ( as mentioned in the previous responses to this post) I have experimented with knife sharpeners and other sharpening gadgets ( not recommended) and every other way you see online to get a razor sharp. The result "fail". Every time! Unfortunately there is no easy way to do it. You need the right gear and you need a lot of practice and patience to home/strop/shave with a straight razor.
