Members CitizenKate Posted April 19, 2009 Members Report Posted April 19, 2009 I decided to start a new topic on something that was posted on another one to avoid diverting attention away from the original topic: You probably already know this, (but if you don't) make sure you've got some white jeweler's rouge to make a little strop with. The difference it will make in the ease of use of the swivel knife is almost as much as having the proper moisture content! And it just takes a couple of swipes on both sides of the blade to polish the little rascal up so that it slides thru the leather like a greased whatever... Hi Kevin, I'm curious why all the leather suppliers sell the white buffing compound, and nothing else? I decided to use the red once, and my knife tips are way sharper and smoother than I could ever get them with the white stuff. And I know there are other kinds out there (like "yellow" stuff and "green" stuff) that other leather workers seem to prefer over the white stuff. Que pasa, eh? Kate Quote
hidepounder Posted April 19, 2009 Report Posted April 19, 2009 Kate, The different colors represent different grits and are often used for different materials as well. I don't use the red much anymore. I polish with the white first and then use the green for a final polish. I use a strop loaded with green rouge for my swivel knife. When polishing with rouge, it makes a difference what grit stone was used first. The finer the stone, the less need for aggressive rouges. When buying the green rouge, one must be careful to get the one intended for steel. There are some out there that the knifemakers use that are intended for finishing wood, brass etc. Maybe some of them coud jump in here and explain this a lot better. Bob Quote
Dale Posted April 19, 2009 Report Posted April 19, 2009 I'm going by memory, so I may be a little off. I think the color has more to do with the material it's trying to cut rather than its grit. The red is typically for softer metals whereas the white and green are more for harder metals. Quote Dale Hietala www.moonlightartstudio.com

Dale...I think you are correct...I didn't mean that the way it sounded. It's just easier to refer to the different rouges by color. I know there is more than one kind of green...only because I ran into that question when I purchased the my first green rouge. Bob Quote
Contributing Member UKRay Posted April 19, 2009 Contributing Member Report Posted April 19, 2009 Kate, This is a very useful thread... I mainly use a red traditional jeweller's rouge because I tend to have it lying about the workshop for polishing newly made silver work. It seems to work pretty well on my leatherwork knives. I do have some white stuff that seems a lot more aggressive so I'm very careful how I use it. Perhaps someone could post a 'chart' of the various colours and their applications? Does anyone use aluminium oxide powder as a sharpening/polishing aid - what does it do and why should anyone use it?

gtwister09 Posted April 19, 2009 Report Posted April 19, 2009 Bob, The answer is both grit and material. Each performs different functions. Some only cut, some cut and color and some just color. Getting one that cuts and colors would be a better choice for general purpose or single use material (like in the use of the strop). I would imagine that long ago there was a greater availability of white compounds than there was of green for stainless steels....thereby the cost was significantly less for white than green. At a high level... grits/color material/functions Black is the most coarse and it's generally used for removing pits, scratches, rust and paint. Brown Tripoli is next in the coarseness range and it is generally used for fast removal of softer metals. White is even finer and is generally used for color and final finish on hard metals. It does have a cutting action. Red is generally referred to as Jeweler's Rouge and is designed to polish without cutting. Blue is another one that is designed for polishing without cutting. Green is generally used for stainless steel for color and cutting. Yellow is another one designed for color and cutting. It is somewhere between white and green. Generally in buffing you have three phases. (1) Rough Cut To Remove Scratches (2) Final Cut & Initial Polish - you should first use your wheel with a cutting action, then finish with a color action. (3) Final Polish - creates luster As denoted above there is a cutting and color motion. The cutting motion produces a semi-bright, smooth and uniform surface. The color motion produces a shiny, bright and clean surface. Cutting motion should be performed against the direction of the wheel with a medium to hard pressure. Color motion should be performed with the direction of the wheel using a medium to light pressure. The same applies to using the strop and pushing/pulling a swivel knife. One cuts and the other polishes. Regards, Ben Quote
Members CitizenKate Posted April 23, 2009 Author Members Report Posted April 23, 2009 Great info, Thanks, guys! But I still wonder... why do Tandy and other leather suppliers only supply the white stuff? Kate Quote
Members Rawhide Posted April 23, 2009 Members Report Posted April 23, 2009 Great info, Thanks, guys! But I still wonder... why do Tandy and other leather suppliers only supply the white stuff?Kate Because Tandy is a corporate owned entity and everything they sell probably has to be approved by some team (probably board of directors)....Probably the same reason they don't sell any custom maker tools like hidecrafters. It's much more cost effective to supply one kind of rouge than to stock more expensive ones... Quote Marlon
HorsehairBraider Posted April 23, 2009 Report Posted April 23, 2009 As a jeweler, who uses different polishing compounds, there are a lot of different ones on the market. If you check out a place like Rio Grande (Rio Grande Home Page ) you'll find lots of different polishing compounds. Some are more aggressive, some lighter... AND some dissolve in water and some do not. I personally use a BLACK "rouge" that is my final polish - it dissolves in water so I can easily wash it off my jewelry. (I don't get it from Rio.) Basically, lots of different companies decide to market a polishing compound. Depending on what they use in it, it will come out different colors, and have different properties. You experiment with them and find out the best ones that work for you. Once you find something that works, well, "if it ain't broke don't fix it", stick with it. I've used lots of them in my career. The "Bruce Bar" is one, there are tons more. As to why Tandy only sells one type, that has to do with their guy in charge of products. That's what that person buys, so that's what they have for sale. Doesn't mean it's the "best". The "best" is the one that works FOR YOU. Quote They say princes learn no art truly, but the art of horsemanship. The reason is, the brave beast is no flatterer.
