HA Strop kit redux

Mon Aug 27, 2012 3:06 pm

It arrived Friday via FedEX. Thanks,Mark. I've used it on three different knives. It's a steep learning curve for me as I have no experience with this type of equipment but wanted to try to learn. I wasn't too impressed at first but I think I didn't have enough build-up of the diamond spray. It's either getting better or I am succumbing to the placebo effect-It's supposed to make knives sharper,therefore it is. How many passes/side shoulkd one make. I am using the strop after finishing on a King 8K stone. Thanks for any advice for a newbie.

It's probably technique or pressure, or not having a good edge to start with.

First, technique for a blade that has been sharpened at the correct angle.

Lay the blade flat on the leather and then push the blade forward on the leather while slowly lifting the spine of the blade.

At one point the edge will bite into the leather - stop right there.

Now, pull back at that same angle across the length of the blade with light pressure and at the end of the stroke STOP and pull the blade up and off of the leather.

Repeat on the other side, back and forth, a dozen times to start and test the blade either by using it for its intended purpose or by slicing paper, hanging string, Etc.

By pushing the edge forward and stopping when the edge bites helps you to find the correct edge to strop at. By stopping and pulling up and off the leather at the end of the stroke you prevent rounding off of the edge that will occur if you should lift the blade off in a arc as most tend to do - including me.

If you find that you are raising the spine of the blade more than a quarter inch to get the edge to bite you probably need to grind, on a typical Japanese knife ground at 5 - 15 degrees you should only need to raise the spine an eighth, maybe a tad more.

Always bear in mind that leather will not make a bad edge good, but will help to make a good edge better.

Anyway, give the technique a try and see if it helps.

Same technique for the balsa/diamond spray?

Forgot to add..Any advice on number of strokes?

Same technique for balsa.

Number of strokes depend on the steel and previous finish. I normally don't do more than 10 strokes per side.

+1, but when the rum speaks, I tend to push it to 15 strokes just to make sure.....overkill I know.........

....rather safe than sorry though, especially if it is M390 steel.....
