1. Extreme noise reduction
   When you think of the straight knives in your original cutter head, they work just like a fan that moves air at very high speeds. This is what is causing the high noise levels when no wood is passing through the machine. With a SHELIX helical cutterhead, the knives are only 15mm (about ½" wide) and the air movement caused by each individual knife causes so much less noise that even the addition of all knives doesn't generate as much noise as one straight knife. When you plane a 10 inch wide board for example, the traditional straight knives will cut these 10 inches straight off which also causes a high noise level. Because of the spiral pattern, a SHELIX head will remove only 15mm (about ½ inch) at any given time, causing a decreased noise level. While the noise level reduction is measurable in db, we cannot put a general number on it as it depends on your machine and many factors (width of the machine, number of straight knives, RPM's etc.) However, many people report a noise reduction of up to 50%.

2. Chip outs are virtually eliminated
   Chip-outs are the number one problem for many woodworkers when it comes to planing wood. Especially some hardwoods such as Maple always tend to show small holes in the surface after the wood went through the planer or over the jointer. This is caused by the straight knives when they start to become dull as the wood sometimes offers such density that the knives no longer cut but break or actually tear wood chips out of the surface. Many spiral cutter heads on the market reduce this problem as only small single knives cut the wood at any given time but this is where the Byrd SHELIX head makes all the difference: The knives are sitting on a diagonal angle on the head and therefore, offer a SHEAR cut instead of a straight cut. This SHEAR cut virtually eliminates chip outs.

3. Your dust collection system works better
   When you are cutting a 10 inch wide board in your planer with a standard cutter head, you create 10 inch wide wood chips that your dust collection system has to suck up. The Byrd SHELIX head only cuts 15mm (about ½ inch) at any given time and therefore, the wood chips are much smaller. Smaller wood chips are much lighter in weight which is why your dust collection system sucks them up much easier.

4. Necessary replacements of knives cost a fraction in most cases
   When knives become dull, you have to re-sharpen or to replace them. In actual fact, most replacements become necessary when a hidden nail or rock in the wood chips out your knives and they now leave ugly and uneven patterns in the wood. When this happens with a Byrd SHELIX head, usually only one or 2 small knives are affected. As the knives are sharp on all four edges, a simple turn of 90 degrees solves the problem without a knife replacement.

5. Knives are made from carbide which will last you up to 40 times longer
   Our C3 carbide lasts an average of 10 times longer than traditional steel knives, never mind that they allow you to also cut man made materials such as MDF and plywood. As all knives are sharp on all four edges, a simple turn of 90 degrees eliminates the need for a knife re-sharpening or replacement. Therefore, these carbide knives will last you about 40 times longer than steel knives. These little insert knives cannot be re-sharpened and once they become dull on all four edges, a replacement becomes necessary. If you were used to re-sharpen your steel knives on average 2 times before replacing them, this means by now, you would have already paid for 13 sets of knives and 26 re-sharpening's (never mind the time you saved).

6. Replacing knives is easy and doesn't require alignment
   As you can see in the picture above, all knives are fastened with a screw through a hole in the center of the knife. The knives are sitting in a matching pocket that keeps the knife in perfect alignment. When installing new knives, simply let the screw guide the knife into the correct spot.
