Description of Knuckle
First released with CX-13 Starter Bahamut Bliz BK1-50I as part of the Xtreme Gear Sports Custom Line Expand Blade on March 28th, 2026, Knuckle is an Assist Blade Blade featuring a five-sided design.
Knuckle is entirely made of plastic, with an overall pentagonal shape featuring 5 auxiliary contact points. Out of the 5 contact points, one is larger, in order to create synergy with the Metal Blade Blitz.
Furthermore, gaps can be found on all 4 regular contact points, which creates (or exacerbates) a focused weight distribution towards the largest contact point.
Additionally, this Assist Blade is fairly thin. As a result, it lowers the combination height. At the time of writing, Custom Line low combinations are usually preferred for an agressive Attack style, while thick, tall Assist Blades are preferred in Defense/Stamina combinations.
While Knuckle can be used with some degree of success in Attack type combos, the combination of plastic and metal contact points can make recoil feel more unpredictable.
Moreover, when compared to Heavy, Knuckle may feel too light for competitive players.
Final Thoughts
While Knuckle creates great synergy with the Metal Blade Blitz, it may be outclassed by other options, such as Heavy and Wheel , because of its lack of weight.
Therefore, this Assist Blade is a nice addition in any Beyblade X collection nonetheless.
