Members rawhide1 Posted January 12, 2009 Members Report Posted January 12, 2009 Now that some gracious members have given me some know how on sharpening my splitter blade. I'm not sure what stone or stones to buy. Hell you've got Japanese, Arkansas,diamond, and probably a few others as well. And they all claim to be the best!! And grits from 300 to 8,000 that I saw. So my question is what would be the best stone for sharpening all my leather tools on. And what range of grit should a fella have. I reckon it would be nice to have 3 to 4 different grits but I'm not sure which. And where is a good source to buy from. So before I throw my hard earned money down I would like yawl's opinion and guidance. Thank you in advance!! Mike Quote
Members jawilliams Posted January 12, 2009 Members Report Posted January 12, 2009 Awsome question!!! To be honest I build and sharpen knives. The last step is using a stone. I use a Norton / India stone. Yes I also use it to put an edge and sharpen my leather cutting tools. I have one of each of the following. 400, 800, 1200 and 1600 or 2000 grit stones. I picked mine up a different garage sales. I couldn't tell you where to get them though. And the higher the number the finer the grit. They have worked for me very well Quote
Members tonyc1 Posted January 12, 2009 Members Report Posted January 12, 2009 I've always used a Norton stone to sharpen my knives and they are great. The bloke who taught me to sharpen was a competing axeman and he said it was used on axes. Mine is a reddy colour one side and black on the other which is used for taking the feather off. Mine is half worn out but I was offered $400 for it last year as they are not sold out here anymore and this axeman wanted it. I make a few axe covers that act as a sheath over the year. I only threw the packet out a couple of years ago and I think it may have even said it was "Bear Brand Norton" Can't remember, "CRAFT" is setting in! Tony. Quote

Members Greywynd Posted January 13, 2009 Members Report Posted January 13, 2009 Stones....oh boy. There are a LOT of different stones, and amongst those, even more different types. My knowledge is better on grinding wheels then stones, but there are a lot of overlaps too. Let's see, where to begin. Grit size. This also applies to sandpaper. Basically, the bigger the number, the finer the grit. Woodworkers, they are used to seeing 80, 150, 240, maybe 400 grit sandpaper at times. Stones can go as fine as 4000, 6000 and finer. Most of teh stone work I do is for polishing purposes, but since it's hardened (sometimes very hard) steel, I would usually go to about 600, maybe 1000 grit with stones, then I would go to a diamond compound beyond that. For sharpening, at least as far as touch up stuff that would be the norm, I would suggest around a 6-800 grit, maybe 1000. You cold step up to a 2000, or if you can find one, something in between first. Beyond that, switch to rouge and strops, or other 'soft' material as a carrier for the compounds. Fine, hard stones, a lot of times called Arkansas white, will often be finer than this, and are great for removing burrs and other touch up work. Stone material. There are different materials used for stones. Aluminum oxide, carborundum, and others, even diamond can be used. Stones are a little different than grinding, as the heat buildup isn't as severe. When grinding, one wants the material to 'break down' exposing a new sharp cutting edge on the surface. If the grit gets rounded over, it no longer cuts, and causes extra heat buildup. Bond. This is basically the 'glue' holding the grit together. Again, you want it to let go when a piece of grit gets dull, but not too easily, or it results in premature wear of the stone. Another term, I can never remember the proper name, I'll call 'density'. If you think of a stone as a sponge, is it full of big holes, or all small ones? With stones, if you are using them wet (regardless if it's water, oil, whatever), you want some porosity to it to hold some of that fluid. Using them wet is a good idea, if you're removing a lot of material, the resulting slurry will help with the cutting action, and help to carry the cuttings and small fragments of stone away. Not enough, and the pores of the stone plug up, resulting in a poor cutting action. Cheap stones...well, they sometimes can be just that. One of the biggest problems will be soft material, and poor bond. These will wear down quickly, and have a short lifespan. Norton is a good name for grinding wheels and stones, most of the other stuff I'm familiar with is from industrial suppliers or diemaking supply places. It's easy to find a variety of 'ways' to sharpen stuff, whether it be knives, leather tools, whatever. What works for one person, might not for the next. Same from one tool to the next. One tool might be a harder steel, and need one type of stone, another a softer steel and require a softer stone. A couple tricks that may come in handy....if you need to shape a stone for a particular use, there are different ways it can be done. Stinky and dusty, a bench grinder or belt sander will shape some stones, but use caution, they can and will break, and also they can 'glaze' over, or plug up as well. An old file will shape some stones, I tend to lay it flat on the bench and run teh stone along it. This takes teh edge off the file in a hurry, hence using an old one, and I always keep one old one around for that job. Also, some stones you can use sandpaper to shape, again, lay it flat on a hard surface, and run the stone back and forth on it. If anyone has any particular questions on stones, or are looking for suggestions how to sharpen a particular tool, just ask, I'll see what I can do. Quote
Members tonyc1 Posted January 13, 2009 Members Report Posted January 13, 2009 I have reshaped my Norton twice. I have used a concrete block on it's side to do the job. Lay the block on it's side and then rubbed my stone on it 'til the high spots disappeared. If you have one of these red and black stones, the red side is for putting the edge on and the black side is for removing the "feather" that is left. I believe these stones should only be used with water or good old spit! Tony. Quote
hidepounder Posted January 13, 2009 Report Posted January 13, 2009 (edited) I use 10" EZ Lap diamond stones. It's 800 grit screen on one side and 1200 grit screen on the other. I like them because they are mounted on ceramic and cut really fast. One or two passes are all it takes with the 1200. It would be very easy to waste a lot of blade with the diamond stones. I need to find a 2000 & 3000 grit stone for better polishing. When I finish honing I buff carefully with three different rouges to create a mirror finish. That being said, I like what Bree said she is doing, in the other thread, and am going to pursue that method also. I think it might be easier and the super fine papers are less expensive.

Members rawhide1 Posted January 13, 2009 Author Members Report Posted January 13, 2009 Greywynd, tonyc1, and hidepounder Thank you all for your help and information. I figured as with everything else in life what works for one may not work for others. That's why it's so good to hear how everyone does it different. So if one way doesn't work for me I have other methods to try that may. Wow Greywynd !!Thanks for all the information it cleared up some of the muddy water!! Mike Quote
Bree Posted January 13, 2009 Report Posted January 13, 2009 Here is some different info for you to consider. Kind of interesting. This sharpening guy has an extensive website with microscopic photos showing you exactly what's going on with a sharp blade. He uses the flat plate (glass) and abrasives method. Pay particular attention to the "wire edge" and its removal. You have to click in on this site as there isn't a coherent navigation system. Make sure to find the Sharpening A-Z link and follow it. http://www3.telus.net/BrentBeach/Sharpen/index.html Quote Ride Safe!

Members Greywynd Posted January 13, 2009 Members Report Posted January 13, 2009 Bree, he has some interesting info on there. Most of my magnification work usually stopped at about 50x magnification, so some of this is rather interesting to me. (Though it may be overload to some!) I'll have to take a look around for the razor blade that I ran a bead of weld along the cutting edge and see if I can get a picture......not that it's pertinent to the topic at hand, just a fun thing to demonstrate some small work.
