BASIC PATTERNS There are several different types of patterns that can be made, and these types are broken down into three different classes: surface manipulation, material manipulation, and the most complex, composite patterns. The "easiestF1of the three is surface manipulation. Surface Munipulution Patterns These patterns are more ox less what the name says: a surface treatment. The patterns tend to be shallow and can be overground, which can in effect "erase" the surface pattern. But when done properly, surface manipulation patterns can be very beautiful.

Careful workmanship and close attention to detail will always be the best way for any craftsman who takes his or her work seriously. Figure 20. Whenproperly forged, a fuller will w m press the laminates, causing them to appear thinner once the fuller is ground and polishedletched. This effecti s similar to edge packing. Patterns hese patterns are perhaps the most difficult and complex patterns that can be made. Even the "simpler" ones use at least two separate pieces of laminate to make a billet, while the more complex useupwards of eight or more laminated pieces io fashion a single bar of a given pattern.

This is more precise than doing it by hand, but a good, even pattern can be hand-cut using either the file or grinder methods.
