After the grinding is done a couple of swipes across a flat stone touches only the edge and the heel and as long as the hollow remains it is easy to lock in on to the correct angle for honing and then a few swipes with a fine slip stone removes the burr.

Hollow grinding simplifies the subsequent honing but the more acute angle that results will make the cutting edge weaker and more liable to be damaged. This detrimental effect is especially noticeable on the very hard, laminated Japanese plane blades and chisels. In Japan it is unthinkable to grind the bevel of a blade hollow.

Grind - Wikipedia. A blade's grind is its cross-sectional shape in a plane normal to the edge. Grind differs from blade profile, which is the blade's cross-sectional shape in the plane containing the blade's edge and the centre contour of the blade's back (meaning the shape of the blade when viewed from the side, i.e. clip point, spear point, etc.).

Mar 25, 2021. #10. Note: Per Allan Lacer and common sense when you hone a hollow ground skew you ride both edges of grind arc and that way there will not be any micro bevel on the cutting edge where as a flat grind can only be honed with a micro bevel. The micro bevel will affect the quality and the control of the cut.

Honing is a precision machining process which uses a variety of abrasives to remove small amounts of material from inside a seamless tube hollow. Honing is a lower velocity abrading process than grinding. Because less heat and pressure is created, the finish, size and precision of the final product is not affected by heat stress.

I have considered a wedge, using my filling jig, but nothing really beats a hollow grind for honing a comfortable edge to shave with. Problem is, I don't have much money to invest further into these knives so a new belt grinder would be a little out of my range. Although I am pretty handy.

A hollow grind means metal is only removed at the secondary cutting edge, as well as at the spine to a lesser degree. As a hollow grind assumes the shape of the outer diameter of the grinding wheel that sharpened it, different diameters of wheel will produce a …

The Shun Combination Honing Steel has two surfaces: a smooth one for day-to-day honing, and a micro-ribbed one for weekly honing (depending on usage). While fine European knives can require honing after each use, Shun's harder steel means you can hone just once a week or so, depending on your level of use. To make honing to the correct 16 ...

Japanese blades are usually hollow ground in the back to minimize the amount of material that has to be removed when honing the back. This does make flattening the back easier, but also can present a problem as the blade is honed and the edge creeps into the hollow ground area.

Sharpening is really two processes: Grinding and honing. Grinding is simply the removal of metal. Honing is a precision abrasion process in which a relatively small amount of material is removed from the surface by the means of abrasive stones. Once you have the right shape, usually using a more aggressive grit, you then switch to a finer grit ...

Most of the hollow-ground knives produced today have a secondary V-bevel at the edge, and so can be sharpened on a stone or other flat hone, or by using a guided sharpening system. Because a hollow-ground blade has the potential to be extraordinarily sharp, however, it can benefit greatly from stropping.

I think it also reflects both a lack of confidence in one's ability with the leather honing wheel and an addiction to grit numbers. I am old enough to have been a charter subscriber to Fine Woodworking magazine in the early 1970s. One of the hot topics back then was hollow grinding. The majority of home shop grinders were six inch. A few were ...

If you use the same area too much, a hollow will develop there, and it won't sharpen edges as easily from then on. After honing the bevel, you may notice a slight recess on the flat side. This is called a hollow grind, and in Japan, chisels are sharpened that way on purpose, because it makes it easier to sharpen them the next time.

Sharpening a true hollow ground knife with a sharpening stone will produce a more durable flat grind at the edge. If you are sharpening a kitchen knife with the indentations on the sides, we also recommend a sharpening stone or a good sharpening system. In short, if you just want to sharpen your knife that is hollow ground (either definition ...

Freehand - Hollow grind style How to Hone a Hollow Ground Bevel - 1900 From the 1900 Shapleigh Handbook, page 39. Grinding "The time to stop grinding a tool is just before the old bevel is ground off." Honing "Let the iron lay perfectly flat upon the stone, with a tendency only to bear harder upon the edge of the bevel than upon the heel.

The microbevel may either be a tiny secondary bevel or it may be a product of honing on the face of a hollow grind. Generally, secondary bevels are easier to do with a honing guide if you are starting out, or if you have no intention of developing the handskills involved. With the latter, lifting the blade a couple of degrees as you move to the ...

The hollow-ground face. The key to honing with this method is to rock the edge up and down on the sharpening stone until it "clicks" into place, with the two ends of the hollow grind making even contact. Then hold it in this position while moving the tool sideway up and down the stone.

The hone line is the thin flat line that you see on the hollow side of the edge that runs from the tip of the scissor to the back. This gives the scissor a smooth and quiet run. If we did not grind on the hone line, the scissor would run hard and loud.

Thick knives are quickly thinned and restored to almost new condition. The benefits of properly tapered knives for a processing plant are increased production and ...

I don't hollow grind chisels and gouges for any reason other than to reduce the width of the honing bevel. If I had a flat honing disc or belt sander to produce a primary bevel quickly, as long as it didn't leave deep scratches at the cutting edge, I'd probably use that, especially in the case of gouges.

A hollow grind will self-jig the blade so that it is supported on the sharpening medium. A hollow grind automatically created a microbevel, which reduces the area to hone, making sharpening faster. Flat grinds are predominantly for those that (a) do not use a grinder at all, or (b) are intending to use a honing guide.

In general: the higher the grade of hollow grinding, the easier it is for the customer to keep the blade in perfect condition with relative ease (stropping and sometimes honing). Flat ground: in general for heavy and less perfect shaving, for contour shaving, hospitals, etc. Full hollow ground: for thorough and precise shaving.

You can sharpen, polish, and/or strop a knife with a hollow grind just the same as any other grind. With normal use and sharpening you might have trouble a few decades down the line when you've removed enough steel that the part of the blade where the primary grind transitions to the secondary grind is too thick for efficient cutting.

The hollow grind is a very common grind for knife blades. The bevel, meaning the ground section of the blade, is much thinner in hollow-ground blades than in convex or flat-ground blades. The hollow grind is achieved by holding the blade to the grinding wheel at a right angle, which "hollows" the blade.

The HG3 Hollow Grinder uses two 6 inch (15.25 cm) cupped wheels to grind the knife blades. The diameter of the wheels never changes with the cupped wheel system which allows knives to be taper ground at the same angle throughout the life of the wheels.
