Editing Pin System (section)

===Tang Pin===

Tang pins work very similarily to [[#Press-fit|press fit zen pins]]. The biggest difference is that a single pin is pressed inside the blade. An example for this type of pin system is the [[Bladerunners_Systems_Alpha_Beast_3.0|Alpha Beast 3.0]].

While there are tang pin balisongs with aluminum handles, such as the [[Squid_Industries_Nautilus|Nautilus]], tang pins generally do not work well with aluminium. This is because the unhardened tang pin is still significantly harder than aluminium, causing the aluminium handles to deform over time. As a result, the handle gap will degrade, eventually leading to [[slap]]

====Heat Treated vs Non Heat Treated Tang Pins====

Tang pins must always be non heat treated, this is because the pin needs to conform to the shape of the hole in the blade during the press-fit process. If the tang was hardened, pressing it into the blade could cause the blade to crack due to the lack of give in both the blade, and the tang pin. Additionally, tang pins directly contact the soft titanium handles. By not heat-treating the tang pin, both materials should have similar hardness, allowing them to deform slightly and absorb impact without causing damange. If the pin were heat-treated, it would be significantly harder than the titanium, causing the titanium to deform and eventually leading to [[slap]].
