I spent about 5 years heavily involved with cutting competitions. This was the transition time when the ABS was getting out, ICCT was developing the standards and BladeSports was taking over. I wrote most of the rules that are in use today. There has been an unbelievable amount of time and effort put into developing the events, knives and techniques in use today and a lot of people contributed. The events from the early days of the ABS competitions right through the Blade Show Championship this year were designed to test the limits of the knife. Heavy power cuts and light finesse cuts must be performed with equal success to place well. In this regard the knives have to be designed to do all these cuts well. Warren Osborne and Gayle Bradley have done more research on the design for competition knives than anyone I know. If you follow what these two men are doing you will be ahead of the game.
Skill vs. Knife:
Both have to be 100% to win at one of todays major competitions. Luck does not play a part anymore. A good example is Jim Crowell. Jim was involved with cutting competitions from the start. For all the ABS years he was a top competitor. He primarily used a traditional hidden tang knife design. Then ICCT took over and opened the competitions up to stock removal knives. Testing and research was done that showed an advantage with a full tapered tang knife design. Jim became a middle of the road finisher in competitions. He felt like he was just not up to the same level of skill with the new guys competing. At a competition in Texas Jim didnt have one of his own knives to use for the event and borrowed one of Warren Osbornes. (This is within BladeSports rules.) Jim won the event. He also changed the design of the competition knives he makes. This is an example where the knife design and skill level of the competitor were of equal importance.
Important factors for competition knife design:
Blade steel and heat treatment still have to be of primary concern. As in the ABS days if your knife doesnt hold up you will be disqualified or receive point deductions for any equipment failure.
Blade and edge geometry will make the difference if you can make the cuts or not. A re-curve edge will perform well on rope cuts, 2x4 cuts and water bottles but cant make cuts that are on a flat surface like slicing a bottle from top to bottom or cutting a rolling tennis ball. Stabbing cuts have been eliminated from BladeSports competition because of safety concerns and it is after all a cutting competition. So the cleaver style blade is often used. This blade shape can offer advantages in weight distribution and balance. By the way Burt Foster was the first to use the cleaver style blade shape as far as I know.
Handle design is critical. If your handle design is to round, you will have to adjust your grip in the 2x4 cuts. By the time you adjust you have lost. The forward lanyard is not only safer it provides a more secure grip by not allowing your hand to slip back on the handle.
I have only seen a few hollow ground knives in competition. Personally I feel there are possibilities here that have not been thoroughly explored. The best performing knife I made for competitions was very slightly hollow ground. I made a platen for my grinder that would be the equivalent of about a 6-foot diameter wheel. I feel like it relieved cutting drag and I plan to do head to head tests in the future against a flat ground blade.
I learned more in the few years about knife design and heat-treating in the years I competed than in the 20 or so before that combined. I would encourage any knifemaker that wants to make the best performing knives they can get involved in cutting competitions. Its fun and you will learn a lot.
The thing is, to be a top competitor you have to have the skill and the knife. BladeSports has 2 cutting schools now each year. One is in Texas and the other in Washington. Check out the web site to get complete information. The schools are great and you will learn a lot from the best cutters in the business.
