Theses are universal stainless steel balisong (butterfly knife) spacers. These latches have pre-drilled holes, are light weight and excellent for custom knife design work. They can also be used to retrofit many existing butterfly knives.
This model is great for general design, weight reduction and/or filework practice.
Designed by Darrel Ralph.
Note: The replacement spacers come as seen in picture. There is no additional hardware or parts provided.
