This is a good book on the basics of Filipino knife fighting which covers very basic information. The illustrations are adequate but at times confusing. The 4 basic attacks of the slash, rake, gouge and rip are discussed, and although I already knew the principles, there was still a hearty discussion. There are a few important key points such as the "Visayan Knife Cutting Do's and Don'ts" and the "17 Slashes of Death". These 17 "Slashes" are the main vascular pathways that, if attacked, will lead to incapacitation. Defensive and Offensive drills are illustrated but author/photographer do not make it clear on who the actual person is that we are supposed to emulate (both wear black shirts). It's a decent book but there are far better titles than this one. It's worth a read but more detail is covered in other texts, such as The Balisong Manual and Advanced Balisong Manual by Jeff Imada.
