And this is important for several reasons. First, in the world of butterfly knives, it is important to maintain as much safety as you can, especially while practicing advanced tricks and aerials, and this is easier when the training drone you are using is the same weight, balance, length, and the same swing as the live blade you would be using.
Second, if you are just beginning and learning to use a butterfly knife, it is better to have a dull trainer than to tape over the edge or try and dull a live blade.
And, if you use a balisong in a martial/combative manner, a matching trainer is of paramount importance to maintain realistic work, and safety of all parties participating, as it is with any kind of knife combative.
One of the best things about the Lucha trainer is that it is on the KVT bearing system, just like the live blade version, thus providing the same exact action while swinging it. And, just like the live blade, the latch has the same positive stop, so it will not contact the blade.
Not only do we sell the 5150TR trainer, but we also keep stock of trainers for Bear & Sons butterfly knives, and a few general trainers for balisongs in stock.
