The reason I go to higher grits pre-HT is because I reason that it's easier to sand/grind a softer steel than a harder one. Alden Cole said: shallow trough in the handle with a wheel to reduce weight and increase epoxy adhesion FYI, lightening the tang and making fit up easier are the only 'real' reasons to do this.
Sharper grains increase stock removal and improve finish by preventing dull abrasives from rubbing and burning the part during stock removal operations. Although the actual finish and stock removal rates from this operation are primarily dependent on grit size, keeping sharp grains in the grind zone benefits both.
A single piece of coarse grit will grind through all your deep gouges while making a bunch of new medium gouges. Then s piece of medium grit will grind through all your medium gouges, whole making a bunch of new shallow scratches. Then some fine grit will grind through all your shallow scratches and give you a nice satin finish.
I belt sand to a clean 400 grit then hand sand with 400, 600, 1000, 1500, 2000. But lately I've started doing this: hand sand to 400 grit, etch, then hand sand with 1000 grit. It gives it a neat looking satin finish. I have several sanding sticks but mainly use a 6" piece of 1/2" micarta that is super flat.

At Chernobyl nuclear accident in 1986, Russia eventually stopped the chain reaction in the reactor after dropping nearly 2,000 tons of boron carbide and sand. Grinding Polishing Lapping Materials
Aluminum oxide Grit can remove deposits from our substrate or blasting surface at twice the speed as sand, without all the health risks involved in the process like in sand blasting machine. Aluminum Oxide Grit manufacturer is great for antiski (designed to increase friction in the surface, and thereby reduce the possibility of slipping ...
Grinding wheels typically are hard with less forgiveness, putting the operator at a disadvantage at the start. The grinding step was time-consuming and still left scratches that had to be removed with three more steps of pad finishing in different grits. This step was followed by using a unified wheel to achieve the desired surface finish.
In the majority of cases, you should begin with a 40-grit coarse diamond-segment that is bonded into a metallic-matrix. After passing over the surfaces a few times using the 40-grit, change to a finer 80-grit and then a 150-grit metal-bonded abrasives to repeat these processes.

Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...

Brown Aluminum Oxide 70 Grit Suppliers Malaysia. The production of single crystal corundum abrasive is small, and it is only recommended for brown fused alumina grinding heat-resistant alloys and difficult-to-grind metal materials. The reasonable selection of the hardness of the grinding tool is the key to obtain a good grinding effect.
– Grit Size… That is the wrong question. The best grit size depends entirely on how much metal you need to grind and how good a finish you need afterwards.

I start with a 36 grit then go to a NEW 120 grit belt . Ill hand sand sometimes at 120 and ht. Afterward depending on the mood and look of the knife Ill either go with belts at 220 and 400 then a scotchbrite or just hand sand after heat treat from 120 up. 120 is a little bit of a pain but if you get a real good first sand with the 120 the other steps go real fast and smooth.
The grit used to grind out the scratch will depend on the depth of the scratch. It is best to use the finest grit you can to grind out a scratch. I suggest starting with 2000 grit. If that is too slow, go to 1500 or 1200 grit and if it is still grinding too slowly, try 600 grit. However, after grinding with 600 grit, you will have to re-grind ...
Grit Size: A smaller grit size denotes course grain which removes material at a higher rate, but with a rough finish. For instance, a 30 – 40 grit wheel can be as effective as grinding. For wood, I recommend you start with a 60 or 80 grit wheel and work your way up to 120-grade disc for smoother finish.

Grit is a type of fine sand, rock, or gravel that's consumed to assist with the breakdown of food. Birds use grit and the gizzard. Together, these work to grind up seeds or grains so that the stomach can process them. Parrots don't need grit to digest their food.

Pay attention to the grit you choose when using sandpaper. Basic sanding will require a sandpaper grit between 40 and 60. If your concrete surface has minor imperfections, you will want to use grit size between 80 and 120. For an almost perfectly smooth concrete finish, consider using an even higher grit somewhere between 200 and 400.

For this reason, finer grit sized wheels are required to grind hard materials and soft materials are best ground with medium to coarse grit size wheels. For most efficient operation, the grade must be adjusted to suit the hardness of the material. As a general guide, the harder the material, the softer the grade of wheel required.
About Grit. Size of abrasive particles called "grit", and it's selected based on finishing accuracy of grinding surface. Grit is specified in JIS R6001, it's denoted by "F + number". (Example: when grain size is 36, it will be denoted as "F36") The lower numbers mean large spacing of abrasives.
As the scratch is lessened, the grit size of paper is reduced from 40, to 80, 120, 240, 320 and finally 600.Once the surrounding material is removed, then the actual polishing can be started. Buffing compounds will be determined by the size of the scratches.
