easy quick sharpening at home!!

I used sandpaper for years but now I Lansky. I always put the sandpaper on the back of a clipboard so I could sharpen as I watched TV.
 
Does this method get the knife as sharp as the traditional edge forward method?
How resilient is the paper? ie. how many sharpenings can one obtain out of one 2x12" piece of sandpaper. How much time does it require to clean the old one off and glue a new one down? Then do you just use water to rinse the swarf away? Is the cost about 2 bucks a sheet for wet/dry 1K grit paper ? When sharpening, is the paper easily cut?
I'm trying to get at economy a comparative value for equal dollars spent, stone vs paper and the time factor for changing the old one out. DM
 
I really believe the Lansky is a lot faster and of course does a better job of the angle. I never cut the sandpaper because I only sharpened on the draw not the push. This gives a small burr that is removed by a strop. The sandpaper doesn't last long and I just swapped the sheets/grits as I worked along.
 
my experance is
3 sheets of 1500 fine is about 5$ at auto store less at big hard ware place
each sheet will cut long ways
seems that the 400 wont last as long but it is not needed as often
the higher grits will last a long time and as shown you can hear them cut
a half sheet of 1500 seems to be able to do 6 to 10 plane blades
and more chisels
knives dont take as long as there is not as much edge to do
i would say a half sheet of 400 to 800 will last through at least 10 blades of 420
that are hogged up
if to jest re shape it then up to 20 times
and same with high grits

i have never used this on any thing other then 420 or plainer blades
some of which i think may have been a harder steel but is unknown

my use has always been mixed with wood working ...
and yes i have used paper glued to a stick
and i have never used stone or paper on a draw to sharp a knife..
i have used circle strokes to rough in a bad blade which has a draw effect

i still take a stone with me if i leave the house
and have used a lansky off and on for almost 30 years
they are a best buy and portable for a hunt camp

as to cost .. i have yet to see a non high dollar stone that did not need to be re-flattened
which is a bummer to do.. so the sand paper is always flat on the glass which is ... worth it..




for the most part i no longer try to get using knives super sharp
planer blades are a diff story ..
and for them the wet dry paper is best value
and as good as any expensive set up
 
Yes, I did and it was quite a setup he had. I think it would not work for knives but great for chisels. He also sharpened on both strokes which I only sharpened on the pull. I never glued the sandpaper down.
 
I have yet to see a Norton or Spyderco stone that needed leveling.
Just pro-rating the paper vs a good stone (50$) I think you come out the same cost in 20-25yrs. The saving seems to be in time spent changing out a used paper. Plus, the sand paper allows the added benefit of various grits. So, a personal preference is in order. DM
 
I used to use plate glass as the backer, and just wet the paper to get it to stick.

I rarely used wet or dry paper, instead I had access to micron rated poly film backed abrasives, such as are used in the automotive industry. The plastic backed stuff lasts forever, I sharpen chisels, plane blades, jointer knives etc and never had a problem.

See what works for you
 
it is like any thing
more then one way to get your deer
and like stones each will find a best way it works for them
this jest is not often used by knife folks..
well- i noted at the factory that Buck uses sand paper to edge a knife..

plastic backed?
i use auto finish paper from auto supply but seems like paper..
 
That's cool and very well organized. I would like one of those angle jigs for chisels.

Glass makes an excellent backing as does a 12" X 12" polished ceramic tile.

Guntotin, You could wet it to clean it or use oil on it? DM

I have a refillable spray bottle with a few shots of Dawn dish soap and the rest is just water. Too much soap and it prevents cutting, too little and you get slurry mud. When done, I just rinse the whole shot in the sink.

I get 1/2 plate glass edgings, or cut offs from my local glass company. The stuff I use is Micron rated 3m 661 film, which is a very finely graded diamond based abrasive, or the alox based 372L film. This stuff rocks, its not cheap but not expensive for what you get out of it. It goes all the way down to 3 micron, which is something like 2400 grit equivalent.

They make optical level stuff too, which goes incredibly fine, I think the finest I have used is .5 micron, which was used to polish out some imperfections on a Stienway Piano. I think newsprint would be more aggressive but there are NO scratch marks left when you're done with that.
 
Guntotin, Thanks, I'll look into it and see what I can find available. 3 micron is 1500 grit,
.5 micron may get closer to 2200 grit. DM

I was just going off 3M's guide. I will say that the better micron rating system has much more consistent scratch patterns than does Grit marked paper, I think the spread between the catch screens must be small, that is, 3 micron film only has grit that fit thru a 4 micron screen and got caught on a 2 micron screen. Where as Grit paper might be anything between a 2100 and a 2400 screen.
 
I was just going by my charts which include micron size. Many of which I've written the companies to verify. DM
 
A follow up on this topic: Guys I tried finding 800 grit wet/dry sand paper in my area, as that was the slot I needed to fill in my sharpening system. I called every hardware store in town, nop only have 600 skip to 1500. Wal-Mart only has 400. Then the big stores, like Home Depot and Lowes, have only up to 400 as well. Then one department clerk suggested a speciality paint stone. I called them and they have it, $1.50/sheet and its 140 miles away. So, one place in a 200 mile radius. Thats the price one pays for living in the outback. Believe, I'll try the mail order stores. DM
 
Gun, Thats where I found it but in a pack of 4 sheets and only one sheet of 800 grit . The pack runs $4.50 and I'll use the 1K grit in it as well . The others will be saved for some other project . Thanks ! DM
I've glued some and used it and it works . The knife will slice it easily during use as well .
