Kanayama 3 problem

I have been noticing lately that my edges seem to have problem for the last 1-2 cm before the heel where the bevel becomes rippled or wavy and it is even amount between both sides. I have determined the cause to be the edges on my Kanayama 3 strop are not beveled. That sharp edge on hardened leather has been defecting the bevel on my razors as I strop them. I have rounded the edges as of this morning and the problem is solved for me now.
The reason for this thread is so others may check their edges after stropping with Kanayama that does not have beveled edges and look for defects as well. Thanks

Interesting (and troubling). I just acquired a #3 and one thing that struck me as strange is how the edges of the cordovan just abruptly stop. There is no "bevel", or chamfer along the edges, so if there's any amount of cupping, then the edges of the leather would "dig in" to your blade. Is this what you think is occurring? And do you think it's easier for the kanayama (having no handles or D-Rings) to cup?

Yes that is whats happening. Its not actually diggging in so much as stretching the edge and causing a wave. I used a sheet of 220 and 600 grit sandpaper to round my edges. I laid the strop flat on the edge of a board and with the sheet of sandpaper rolled I filed the edges on both sides with 220 grit and then repeated with 600 grit. I just did this morning but it seems to have cured it. I don't have the skill the cut a bevel with a blade....

i don't think any of my kanayamas have beveled edges, i'll have to take a look to see if they are affecting my blade.

I don't think it was a problem in the beginning. I have only noticed lately within the last week or two and have not treated the strop with anything other hand rubbing before stropping most times.
 
I was just given a Kanayama 3 for my birthday last week. I have used it almost exclusively and have not had a problem yet. How old is your strop?
 
Mine arrives today

Can you possibly take pics of what it should look like, vs what they do look like?

Ill try to take some of mine.

Would adding D rings take away from the authenticity you think?
 
I'd give the back of a spoon with some friction and pressure burnishing a shot before taking sandpaper to it, personally. It actually does a whole lot of good on outer edges, without grinding into the leather.

I would be afraid of losing too much stropping surface by adding D rings.
 
I have used mine for about 6 months and have not had a problem at all.

I think barber ends are less likely to cup if the strop is held correctly. The way I hold it is standing off the the side, holding only the leather of the suede, palm on strop fingers over the edge. This hold actually leads to a slight rounding of the leather and puts the edges "down"
 
Curious as to why this is only showing up at the very heel of the blade. Wouldn't the edge of the strop also affect other parts of the blade? Maybe the blade is transitioning from the raised stabilizer with a slight drop onto the edge of the leather? Anyway, you solved the problem.
I haven't experienced this with my #3 but I've only used it about 30 times.
I did have to bevel the edges of an Ambrose Spanish horsehide strop I have because it was prone to cupping and I could feel the blade drag on the edge of the strop.
 
I found an easy way to bevel was to use an injector razor. I removed the nicks on my first strop that way and it was easy to control the amount of material removed.
 
Funny thing - I just 'de-edged' my 80K - I used a small piece of 1k sandpaper. Just a bit of pressure on a 45° angle did it.
I guess you could say what I did was like beveling, sorta.

It felt 'sharp' at the edges when I was running my hand up/down the leather before stropping.
There was no grief to my razors edge, at leat none that I saw - but I didn't like it so I just dressed it down.
That sharpness wasn't there when I got it - I wonder if it happened from stretching and use? Whatever - no big deal really.
It's a natural hand-made product - I expect some 'stuff' to happen over time.
My 70K seems fine, but it's newer.

The way i stop only the affected area leaves the strop in order for the toe to make full contact. Small x strokes while stropping. So its only where the edge of the blade is riding on the edge of the strop.The edge of my Kanayama is quite hard although pliable still.

your describing what was going on with my strop. so I am not alone. Perhaps it was just a matter of time til it started to degrade the edge on your blades where the edge of the strop made contact.
