YOU CAN'T CHOOSE YOUR TIME OF PERIL
Sijo Waysun Johnny Tsai brings 25 plus years of hands on teaching experience. Well known, respected, and appreciated, this quiet professional brings his students a wealth of world class knowledge and experience. According to the Chicago Sun Times, "Tsai's kung fu has been world renowned for world class instruction since 1964" Johnny notes, "we are a Chinese kung fu CUMA combative street defense center."
In addition to full attention to his responsibilities as a respected martial artist, Johnny interacts, regularly trains, and advises numerous law enforcement officers, military personnel, VIPs, and other notable persons that prefer not to be mentioned. There is also talk about overseeing several action film projects on the small and silver screens. Johnny's input to the design of the CUMA Evolution Knife, was welcomed by TOPS staff. Hard work, testing, and refinement went into this fine knife. We at TOPS Knives are proud of our association with Sijo Waysun Johhny Tsai.

Customer Reviews
great blade the wife ordered me one for our anniversary. It was not doubled edged and the grind goes all the way up into the laseretch. I suspect ill be sending it back for a replacement!
This is an excellent knife well worth the money with or without a sheath! The knife is weighted, well balanced and designed by one of the greatest combat martial artist of all times. "Two thumbs up!"
The knife fits loose in the sheath it doesn't grip the blade at all. It is secured by a single Velcro strap that doesn't hold very well. Would be nice if ether the sheath gripped the blade to hold in place, or have a snap or better gripping Velcro to secure knife in place.
This is my new favorite knife!
