Forge Disc - Knuckle
Main article: Forge Disc - Knuckle
Knuckle is a circular Forge Disc with six notches around the perimeter and four holes near the center of the Forge Disc. The letter "K" is written on its prongs for easy differentiation from other Forge Discs. Due to the holes in the Disc, most of the weight of Knuckle is focused around its perimeter giving it high Outward Weight Distribution (OWD) which results in excellent Stamina properties. However, it lags behind other Forge Discs like Spread and Gravity in terms of Stamina potential.
Although, one advantage Knuckle holds over the aforementioned Forge Discs is increased Burst Resistance which only falls behind Down and Armed, both of which suffer from scraping issues and low Stamina respectively. Due to its good Stamina, decent weight and high Burst Resistance, Knuckle was once an excellent Forge Disc for all kinds of Combinations. However, Knuckle has one major weakness, the protrusions nullify Life-After-Death potential which is detrimental in the current Life-After-Death centered metagame.
Performance Tip - Impact
Main article: Performance Tip - Impact
Impact features a star-like rubber tip, with three points. The plastic of the Performance Tip extends between these three points on the rubber tip, filling in the space left by the rubber tip.
However, these plastic fillers cause Impact to be hard to control and effectively reduce its Stamina, due to the fact that two different surfaces are contacting the stadium simultaneously as well as successively, effectively worsening the friction with no real benefit compared to a Performance Tip like Xtreme. Consequently, as a flat tip, the ridge on the perimeter that comes in contact with the stadium floor always gets halted at each change of material: speeding up with the rubber, then slipping and slowing down with the plastic, and so forth.
Impact has three rubber points with three plastic points filling in the gaps between the rubber the plastic makes Impact’s movements uncontrollable. The two different surfaces contacting the stadium simultaneously worsens the Stamina significantly. The rubber making contact with the stadium increases speed, then when the plastic makes contact it slows and decreases grip with the stadium. Because of this, it is not recommended for any Combination.
