diamond-coated bench stones basic equipment as an alternative to japanese waterstones one could also use diamondcoated sharpening devices as a basic equipment a combination stone with 1000 and 6000 grit is sufficient no 711006 for more demanding tasks stones with 220 grit no 711010 2000 grit no 710991 and 4000 grit no 711021 as well as a very fine 8000 grit polishing stone no 711004 are recommended a cleaning stone »nagura« no 711302 can be used to produce a polishing paste 1 2 the diamonds are applied to an extremely flat warping resistant and unbreakable base plate in this way diamond stones are extremely wearresistant and stay flat no more hollows no more trueing the high quality monocrystalline diamonds guarantee remarkable sharpening speed even when working the hardest tool steels like hm hss and pm steels we recommend moistening diamond stones with water and grinding with little pressure made with high-quality monocrystalline diamonds dmt stones usa are especially

trueing of waterstones when sharpening tools with straight cutting edges it is essential that the sharpening stone is completely flat check that the stone is plane by placing the edge of a ruler no 707290 on top of it if light shines through at any point the stone is uneven and must be ground down using one of several methods the easiest of these is truing with a diamond lapping plate no 705429 or no 711613 you rub the well-soaked stone in circles on the lapping plate until the surface is level light surfaces show the even areas of the stone while the darker areas have not yet had contact with the truing block repeat the process until the surface is all light constantly flushing off the paste 1 as an alternative you can use a truing set no 711115 with 100 grit water sandpaper placed on a flat granite stone plate a specialized truing grille no 711297 functions similarly 1 2 storage of waterstones 2 when storing synthetic stones you must differentiate between those that need to be

honing the term honing refers to the process used to remove the burr created during sharpening before beginning rinse the blade to remove the particle remains of the prior stone for honing use a stone with a minimum grit size of 4000 place the blade lengthwise onto the stone and grind it in the direction of the cutting edge at this stage the blade can be held at a slightly steeper angle 1°-2° than that used for grinding to ensure the burr is removed completely as a rule a few light strokes are required on each bevelled edge in alteration before the burr can no longer be felt with the fingertips with increasing delicacy reduce the amount of pressure placed on the blade too much pressure will distort the finely ground cutting edge when finished rinse the knife thoroughly in warm water carbon steel blades should be treated with a little oil to prevent rust check if you rinse with water regularly the stone has its highest efficiency if you rinse less some slurry will build up this

sharpening with the tokico knife sharpener the majority of commercial knife sharpeners are not suitable for japanese high-quality knives one exception is the tokico® knife sharpener no 705373 with this tool all singleand double-bevel blades can be sharpened easily and quickly simply moisten the blade and pull it through the slits 3-10 times the attainable degree of sharpness is limited by the relatively coarse grit 400 of the stone 1 1 1 2 to achieve the required high level of abrasion use a coarse stone 220 grit or 400 grit a coarse diamond block or a water-cooled grinder e.g tormek t-8 no 716034 or shinko no 716020 1 damaged blades damaged cutting edges and broken tips are not reasons to discard much-loved knives finely ground very hard japanese knives in particular can suffer an occasional nick when handled roughly place the blade perpendicular to the stone and grind the entire length of the cutting edge down to the damaged spot the bevel can now be ground onto each side of

tools japanese blades can be trued on diamond blocks no 705382 or using a steel lapping plate no 713600 and silicon carbide powder no 713603 or no 713604 for sharpening tools the same types of stones used for knives are sufficient chisels and plane blades for chisels and plane blades to work effectively their backs have to be absolutely flat the back of new tools is often not 100 even or still shows traces of grinding from the manufacturing process to obtain a sharp cutting edge the back must be smoothed depending on how deep the grinding traces or how even the back is it may have to be roughened first western chisels and plane blades can be trued on a diamond block e.g no 705358 in which case it is sufficient to true the first two-thirds of the back after that the back is ground further with finer grit stones and honed with the finest sharpening stone on the lapping plate the blade is worked with silicon carbide powder and water under high pressure for easy pressure distribution a

finally polish the back with 10-20 passes using the ruler trick to resharpen you hone the secondary bevel and polish the back using the ruler trick template for setting bevel angles stop block honing jig e.g no 711400 bench top stop with time the secondary bevel will become wider and wider i.e the surface to polish becomes larger to speed this up from time to time you should regrind the primary bevel on the coarsest stone you have to such an extent that the resharpening goes quickly alternatively you can use a honing guide and self-adhesive abrasive paper e.g no 707574-707577 stuck on a granite stone plate no 711294 by putting a wooden shim in between the stop block and blade you can increase the bevel angle e.g to hone the secondary bevel onto the blade 1 2 25° 30° 1 you can also sharpen chisels using the lie-nielsen method but not with the ruler trick the back of a chisel must remain absolutely flat as it serves as a guiding surface in precision work 26 2 54 mm 40 mm 35°

sculpting tools carving gouges the outside of a gouge is sharpened on conventional bench stones using a kind of rolling movement this technique requires some practice but provides good results depending on the degree of wear nicks you will either need to pre-sharpen the gouge on a roughing stone or just hone it on the sharpening or honing stones • place the gouge in the middle of the bench stone with the bevel side down • roll the gouge lengthwise over the bench stone to reduce the risk of cutting into the relatively soft stone you sharpen at right angles to the cutting edge with a slight turning motion while maintaining the existing bevel angle as precisely as possible the insides of gouges are normally polished by the manufacturer so it should be sufficient to hone them on an 8000 grit multiform stone hold the gouge with one hand and move the stone with the other from the inside outwards towards the cutting edge let the stone rest on the inside surface and make straight

for outdoor tools like axes sheath knives or pruning shears compact retractable multipurpose diamond sharpeners are particularly practical e.g the dmt® diafold® fine/coarse no 705391 1 1 axes hold the axe securely with one hand or clamp it and move the folding sharpener over the blade from the front or from the back less risk of injury make sure you keep the shape of the bevel curved or straight the radius of the blade is adjusted to the axe‘s purpose and should be kept sharpen double-bevel axes from both sides following this rough pre-sharpening hone with a 1000/6000 combination stone e.g nr 711005 2 2 34 honing the back • hold the drawknife securely in your hand or fix it with a clamp • pre-sharpen the back with the dmt folding sharpener • shiny areas indicate the even parts of the stone while the darker areas have not yet had contact with the sharpening stone or folding sharpener the front part of the blade approx 3 mm is important here • move

caution if you guide the razor with the blade at the front you will cut the strop maintenance products and accessories after sharpening each blade needs some special care to prevent corrosion apply an acid-free rust-prevention oil like camellia oil no 705280 or ballistol no 705270 for removing dirt or grime we recommend the polish and whetting paste gundel-putz no 705262 for cleaning resinified tool blades we recommend ballistol resin solvent no 705524 1 2 right wrong 3 4 • just before you reach the end of the strop turn the razor over do not lift the razor off the strop but roll it over its back this keeps the razor in contact with the strop 1 right wrong • repeat the same movement drawing the razor in the opposite direction with the back of the blade facing towards you when you reach the end of the strop turn the razor over its back as described before 2 3 4 a thin application of oil does more than prevent rust it also improves the running action of many tools like
