Thread: Will grinding tho round-point off ruin temper?

If I gring the round-tip off, to make it a spike, will it ruin the blade's temper?

Not if you do it properly. Go slow, and have water on hand.

If your going to try altering your blade on your own I highly suggest grinding without gloves...If your hands cant handle the heat niether can the blade. For best results make 2 swipes on the grinder and dip in H2O if the tip becomes red you've gone WAY TO HOT! Blade should not change color to keep proper hardness.

What type of razor is it?

Agreed, if the steel changes to any kind of color, you've altered the temper.

I guess you can't grind off the round point if you don't have one.

It isn't hard to grind down a point by hand. I've done it with a 220 grit stone. It does take a bit of time but it doesn't heat up either. If you are not use to grinding, I would recommend the slow way.

When I take grinder/cutter to blade, I do it with a constant water stream on the blade to lubricate/cool the cut. The water slows down the process, and you cannot use cardboard sanding drums because they will disintegrate from the water. I use stone wheels and diamond cutters. If all you are doing is blunting the tip to avoid spike bite, just use a cheap hone stone from K-mart and roll the tip by hand. Don’t try to use a soft stone like a Norton or you will cut a groove in the stone and ruin it.

Let me ask again, what brand razor is it? If you say double duck or wade and butcher, you had better run for your life.

I agree with what everyone else has said so far. If you are lucky enough to have a friend who owns a Tormek and will let you use it, that's your best bet. The Tormek is a low speed, water cooled, electric powered stone wheel. I would never use mine to sharpen a razor, but reshaping a blade is perfect on one. It will NEVER draw temper from a blade.

I would be grinding off the round-point off a Dovo or TI...I don't have a water-cooled grinder, just a normal high-speed bench grinder and a small cut-off tool with grinding wheels, which is also very fast and not speed variable. I guess I could dip th blade in water every second or two, but I'll tell you what, that metal heats up quick (I've not cut a razor, just scrap steel) if your hand is near where you're cutting you'd have to drop it in about a second...so I'm guessing >100 degrees...I wonder what temp ruins the temper? and is 100 degrees too much? What is the max temp?
