Twice As Sharp® Operators Manual
OPERATORS MANUAL TWICE AS SHARP® Scissors Sharpening System Customer service 1-800-888-3832 Professionally Sharpen Scissors and Shears manufactured by WOLFF INDUSTRIES, Inc. BACKGROUND INFORMATION ON LEE WOLFF Inventor of Twice as Sharp® 1930 - 1996 In 1957 Lee Wolff started a sewing machine sales and service business. Fabrics and a complete line of sewing needs were added in 1963, and the number of employees grew to 25 to handle the volume. During those years, Lee did a great deal of scissors sharpening and repair and made im- portant modifications on the available scissors sharpening equipment. In 1971 Lee and Mary Wolff became the first major importer and distributor of plastic handled scissors in the United States. They started to manufacture sewing scissors in 1973 under the trade name of KNIP. A U.S. patent was granted on the KNIP. The scissors factory was sold to American Scissors Corp. in 1980 and moved to the south. Lee set up the factory and innovated many new manufacturing processes. The July 1983 Consumers Reports rates the American Scissors designed and produced by Lee Wolff as a best buy. He also designed a full line of unique plastic handled scissors with interchangeable parts. Lee worked on perfecting the process of scissors sharpening for many years. It is necessary to accurately control the cutting angles, reduce burr formation during sharpening, and do deburring and micro-sharpening as a final process. This method produces scissors that are normally twice as sharp, hence the name Twice as Sharp® scissors sharpener. A United States patent has been granted as well as several foreign patents. -
15 Degree Sharpening Module for Use on Chef’Schoice® Model 2100 Commercial Sharpener
INSTRUCTIONS 15 Degree Sharpening Module for use on Chef’sChoice® Model 2100 Commercial Sharpener Module shown inserted in Model 2100 Sharpener. (Sharpener not included). Read these instructions before use. It is essential that you follow these instructions to achieve optimum results. © 2011 EdgeCraft Corp. INSTRUCTIONS FOR USE OF 15° SHARPENING MODULE EdgeCraft offers the 15° detachable sharpening module designed specially to place a factory quality edge on Japanese, Asian style knives and all other 15° knives. It can be used inter- changeably on the Model 2100 Sharpener with the standard 20° module designed for the European/American style blades and all other 20° knives. The 15° module is identical in size to the 20° module and it can be removed or installed on the guide rails of the Model 2100 as described in the Model 2100 manual. The 15° Japanese/Asian module can be used for either straight edge or serrated edges, how-ever the 20° European/American module is recommended for sharpening serrated blades because serrated blades are predominantly manufactured with 20° edge angles to provide greater support for the individual serrations. While Asian style knives have historically been sharpened at about 15 degrees at the factory and European/American style knives have been made with 20 degree edges, very recently leading German factories have introduced European style knives edged at 15°. Remove the standard 20° European/American module from the 2100 sharpener and install the 15° Japanese/Asian module as described in the Model 2100 Instruction Manual pages 11-12. Understanding THE DIFFERENCE – EUROPEAN/AMERICAN AND Japanese/ASIAN STYLE KNIVES In general you will find that Euro/American blades shown in Figure 1 are sturdier than the more delicate and thinner contemporary Asian blades as illustrated below. -

Saws from Festool. We Are Taking Over the Lead
SAWING Product range Saws from Festool. We are taking over the lead. Perfection is our declared aim. If there will perhaps never be the perfect saw, we have already made history along the way: for example with the guide rail and the splinterguard for circu- lar saws, the triple saw blade guide for pendulum jigsaws or the twin column guide with two bearings for the KAPEX sliding compound mitre saws. We have learnt one thing from this: It is better to set standards than to following existing trends. Our engineers are the driving force behind all innovations. And, of course, our customers. Because only you can show us the way – to tools that are ergo- nomic in shape, lightweight, powerful and operate intuitively. In brief: to a sophisticated and well-thought out system that makes your work decisively easier. We shall remain true to this principle in the future: whether it be through the intensified use of our EC-TEC motor concept and the battery technology in the area of sawing or through further developments that meet our toughest demands. But for all the praise for our products receive here is constantly that little bit of self-criticism. An essential requirement for our aim: the construction of the perfect tool.

The Razors-and-Blades Myth(s) Randal C. Pickert The razors-and-bladesstory offers a foundationalunderstanding of a key area of economics and strategy: invest in an installed base by selling the razor handles at low prices or even giving them away, then sell the razor blades at high prices to justify the prior investment. Large chunks of modern technological life-from VCRs and DVD players to video game systems like the Xbox and now e-book readers-seem to operate subject to the same dynamics of razors-and-blades. The actual history of razors-and-bladesis much richer than the standard story suggests. At the point that Gillette could most readily have played the strategy-from 1904 to 1921, during the period of the initialpatents-it did not do so. The firm under- stood to have invented razors-and-bladesas a business strategy did not play that strat- egy at the point that it was best situated to do so. -

[1] Introduction This report presents the results of a series of tests done on various aspects of knife sharpening. It is divided into sections devoted to each aspect. Each section terminates with a set of conclusions and a Summary of these conclusions is presented at the end of the report. This work has concentrated on evaluating the effectiveness of various knife sharpening techniques by examining the sharpened edges of the knives in a scanning electron microscope, SEM. Much can be learned by examination of a sharpened knife edge with a magnifying glass or an optical microscope, particularly the binocular microscope. However, the optical microscope suffers from a severe limitation. -

Basic Plane Blade Sharpening
BBASICASIC PPLANELANE BBLADELADE SSHARPENINGHARPENING We get a lot of questions about sharpening. Woodworkers have strong, often confl icting, opinions about the right way to sharpen. We’ve taught many beginners to get a razor edge in minutes, using a simple method that gives reliable results. Here it is. A sharp edge is the intersection of two polished surfaces, so you need to work both the bevel and the back of the blade. FForor tthishis mmethodethod yyouou wwillill nneed:eed: •1000 & 8000 grit stones, or equivalent.* •Side Clamping Honing Guide •6” Ruler, approx .020” thick •Protractor •Wet/dry sandpaper – 120-220 Grit * Stones must be fl at. If your stone is used, please refer to the “To Flatten Your Stones” section. BBasicasic TTechniqueechnique (with blade in decent condition) Lie-Nielsen blades are delivered ground fl at, with a bevel of 25°. Other blades, especially old ones, may need work on the back and bevel on coarse stones fi rst to establish a fl at, straight surface. 11.. Set blade bevel down in honing guide at 30° using a protractor. Note: If you record the length the blade projects from the front of the honing guide, then you can re-set it next time to the same angle without the use of the protractor. An easy way to do this is with a simple stop block attached to a small piece of plywood or MDF: Stop Block Bench Top Stop 22.. Hone on 1000 grit until wire edge/burr forms on back of blade, about 4 strokes pulling blade towards you. Distribute wear ev e n l y by using the full surface of the stone. -
