Sharpening is a trick to increase the apparent sharpness of an image by increasing the contrast around areas that look like edges in a photo. There are many reasons for doing this, the most obvious of which is that judicious use of sharpening can make a photo more pleasing to the eye. Image resizing also tends to soften edges, so it is often necessary to sharpen an image after resizing.

Your image should be sized to 220dpi at the size you're going to print it. Zoom the image to 100% so that you can see every pixel in an area of your image. Select Filter/Sharpen/Unsharpen Mask. Adjust the sharpness parameters without over-sharpening. Typical values are 100-150%, 1-2 pixel radius, and a 0 level threshold.

A - This comes down to personal preference. Some players sharpen them every game while others may only sharpen them a few times per season.

Speedheater scrapers are only beveled on 1 side. The following methods can be used to sharpen the blade: Remove the blade from the handle. Place a piece of sandpaper (150 - 220 grit) on a flat surface, and rub the back (non-beveled side) of the blade in circles. This method is the simplest, but if the blade is very dull, it can take some rubbing, since you are wearing away the backside of the blade.

It is highly recommended to replace the blades rather than sharpening them. Once a season is a good time to do it or when dull. Sharpening the blades will reduce their balance, which will increase mower noise, vibrations and can lead to damaging the mowing motors as well as shortening the available work time for a fully charged battery pack. PowerMow.com recommends that you replace your blades at the start of every mowing season to assure a quality cut year after year.

How often you sharpen your knife and how you sharpen your knife largely depends on what you were cutting and how many times you cut with the blade. However, MIL-TAC highly recommends frequent light sharpenings and never let the blade become completely dull. This will ensure that your blade is always sharp. Dull blades are far more dangerous than sharp blades and can cause problems and even injury during use.

Technically, any fine grinding stone will sharpen your katana, but usually is not recommended. this is because you want to keep the clam shape fo the sword, and not have a slight wave (if done improperly). Use a ceramic cross-bar knife sharpener with crossbeams, so that both sides are sharpened at the same time. It will also take fewer strokes to sharpen a blade this way, which saves metal.

Even though it looks like you can sharpen the Fantastix, it is not recommended. Think of them as a cross between a paintbrush and a marker.

You can use a small diamond file or a stone in each flute of the cutter. Some cutters are made in such a way that the backsurface of the cutting edge is not flat but rounded which makes it much harder, and which is why I don't like certain mills. Try not to touch the front surface of the cutter if you can avoid it, they need to be even and square. If necessary, remove the center barrel, set the cutterhead down on a stone and move it around a little, VERY LIGHTLY is the key word here.

Be sure to maintain the same angle for each stroke (we recommend a 20? angle for a good, general-purpose edge). Start strokes with heavy pressure, then ease off to a lighter pressure and finish with a light stroke -- both sides. NOTE: Never use a power-driven grinding wheel to sharpen your knife. This can heat the blade to the point where its temper (a hardening process accomplished by heating and quenching) is damaged.

How frequently the stones must be sharpened depends on how much you grind. Stones can be dressed anywhere from every few weeks to only once a year.

Improper polishing can ruin the artistic and monetary value of a sword; it is best left to professionals. Please read the sword care and NBTHK care manual pages for advice on the proper care of a Japanese sword. Check the sword links page and look for sites offering sword restoration services by trained and qualified persons.

The MBX belt tips can be re-sharpened by reversing the belt in the housing (angled tips are facing backwards) and running the belt lightly on a grinding stone or on a concrete surface for 30-45 seconds. During the re-sharpening process, it is important to hold the belt tips flat so they can be sharpened at the correct angle. Fine (straight tipped) belts only need to be periodically reversed in the housing without applying them to a grinding stone.

Lasers cut, they do not sharpen. The kerf (material cut away) of an industrial laser averages .008 inches. A good edge is finer than this. Additionally, the heat involved would damage the temper of the edge. There is no such thing as laser sharpening.
