Hi All,

I use my kukris, ok most of them :) Therefore I need to sharpen them. In the begining I was using mousepad/sandpaper method. Which worked well for 12 inch kukri, but was eral tiring and time consuming when I had to sharpen 16 inch or longer kukris using the same method.

Flexible sandpaper block was the obvious solution, and as I understand Pendentive is usingthe same method to sharpen his kukris :)

I've sharpened my 18 inch Ang Khola using flaxible sandpaper block and since the kukri was completely dull because last time I've had to use it real hard Iv'e started with 220 grit then used 600 and finally 1000 grit. Fisrt of all it was a lot faster compared to mousepad. You do need to get used to this sharpening technique, but pays off very well.

Now my question. The block I've used is this foam block - KT-77552.

The only problem I have with is, is that the sandparer is held in place with glue. I mean the surface of the block is sticky. Applying is no prob, peeling off the old one is a little bit more troublesome, but no biggie.
However, I am concerned that the glue will eventually go away, and then...
One option is to buy new block, btu I am not sure how often or how long this will last, considering the price 14$ USD may ne be very economical solution.
Another option is to buy the same kind of glue, and apply it as necessary. Does anyone know what substance and where should I get for that?
Third option would be to get another flexible block, if someone could recommend I'd really appreciate :) Block with clips probably to hold sandpaper.

Unfortunately local homedepo has nothing as usual. I've been there 4 times in last 6 months, they never have flexible blocks. And with online stores the problem is that quite often it's difficult to understand by description, whether the surface of the block is flexible or not.
 
Some thoughts:
1) I've seen self-adhesive sandpaper. There are the round sheets for random orbital sanders, but also ones in rolls. Just cut off what you need. Flaw: not sure if it's available in the really high grits?

2) Use a conventional rubber sanding blocks, the kind that has nail-like things to hold the ends of a strip of sandpaper; just glue a mouse pad to the bottom to give it some flexibility and give. Flaw: watch your fingers.

I've not tried either of these. Your post got me thinking. I REALLY like the handle on the sanding pad you like. It ought to help keep those fingertips attached.
 
Glue idea: Perhaps try rubber cement. Not contact cement like for attaching laminate countertops, but I've seen some stuff that's more for hobby / craft stuff. A guy recommended it to me for mounting photos. Nice and sticky. Doesn't dry hard, but dries to, well, rubber. Things can peel off easily, and the rubbery residue peels or rubs off too. Please don't try this until / unless your block loses so much of its sticky it doesn't work.
 
Gator, I tried and tried and couldn't get mousepad material (even over wood) to work for me. It seemed, the more I tried to sharpen, the duller the edge was. I have switched to using just plain 1/2" celluloid foam (packing foam) and adhesive backed 3M gold disks in 150, 220, 240, & 400grit (I cut them up in squares) I had for the 6" orbital. I've also been experimenting w/ crocus cloth and different grits of wet/dry and only use my kids 'stick' glue as an adhesive.
I haven't had any problems with the paper coming off and my edge sharpening skills have improved greatly. While I dont recomment this, I've also been experimenting w/ using sandpaper alone (very lightly) w/ my finger tips as the cushion. Again this is ONLY for feather-edging and is done slow.
just my $.02
 
go to an auto body&repair shop store or auto paint shop, they have self adhesive sand papers in super fine grits and also more corse grits.
 
Nismo is right...the premium paper at Autobody supply stores are the ticket. They cost a little more, but for a reason. I've used plane jane 320grit on a Kumar Balance that did nothing but make the edge 'shiny'...I thought I was loosing my mind. The 240grit 3M gold however, removed metal in that case. ;)
 
I tried the sand paper over foam and did not work too well for me either. I switched back to my trusty pocket diamond rod and finish with leather over a wood block. Able to shave hair off my arm with my 16.5 WWII. Maybe I'll try the Croc. Dundee trick later!
