How long weapons, such as staff and spear, can help you develop speed and power with your shorter weapons, such as sword, stick, knife and hand.

The purpose of this series is to learn how to learn; ie the teachnique of learning something new. One way human beings do this (especially when young) is by learning through comparisons. In this essay we will examine the differences in drawing three categories of weapons; the bowie, the kukri and the hatchet/tomahawk.

If I ever had to use a bowie knife for defensive purposes, I’d want to cut with maximum effect at the longest possible distance. This means putting the Center of Percussion (C.O.P.) as far forward as possible; while still retaining a functional, piercing point (1). Therefore, I’d want to have a relatively short false edge or swedge (2). For most of my bowies, it seems that a swedge length between 1/4 and 1/3 of the overall blade length strikes the right balance.

The main purpose of Pekiti-Tirsia hand vs knife training is NOT to end the fight against a knife with your bare hands. The purpose of any good hand vs knife system should be to buy you enough time to make the fight your weapon vs his weapon as soon as possible.

Here is an article I wrote for the July 1999 issue of Inside Kung Fu magazine on the subject of knives for self defense use. I was specifically writing about a pet peeve of mine in the 1990s. Some instructors back then were teaching techniques developed in the Philippines and designed for use with a large blade, but were teaching the same techniques to their students in the West, who are carrying much smaller knives. My problem with this was expecting the small knife to be able to do the work of a much larger blade. Like much else in life: SIZE DOES MATTER!

I’ve been traveling to Finland since the mid-1990s to teach Pekiti-Tirsia seminars hosted by my friend Sensei/Guro Kaj Westersund. Here are some of the knives he and his students have given me, along with a look at my 2009 trip to the shop of Finnish custom knife-maker Markku Vilppola; as well as a look at the Finnish military Ranger knife designed by J.P. Peltonen.

The purpose of this essay is to help you find a knife handle that will fit your hand by filling in the information often missing on handle dimensions in the specifications on knife maker’s website. 

Dear Certified Firearms Instructor: Think of this article as a way to help decide which tools you should pull from your toolbox first, when teaching LEOs and CCW citizens basic handgun defenses against a knife, coming from someone with long experience in both types of weapons.

The way I teach Pekiti-Tirsia advanced hand vs knife has evolved over the years.

When I first learned the system from Grand Tuhon Gaje, hand vs knife was divided into two stages:

Back in the 1970s, when I first started learning Pekiti-Tirsia knife work, Tuhon Gaje had us do many exercises to strengthen our grip. Things like doing push ups while holding our rattan sticks with the butt end braced on the floor, as well as striking and thrusting our sticks full power into a stack of car tires.

Knife work is inherently "dark" and it is all too easy for your students to go over to "The Dark Side" while training in it. While I want my students to take their training seriously (and the consequences of their actions VERY seriously), I don't want them to take themselves or even me too seriously. Here is the danger I am trying to avoid. What should be a defensive tactics class that simply focuses on one practical defensive tool, can easily be turned into "The Cult of the Knife.”
