A combo is not just three strong parts. The important question is whether the Blade, Ratchet, and Bit support the same battle plan.
Blade
The Blade is the main contact piece. It affects how the combo hits, absorbs contact, and carries weight through collisions.
Ratchet
The Ratchet changes height and can affect burst risk. It is often the tuning layer between the Blade plan and the Bit behavior.
Bit
The Bit is the movement and stamina piece. Flat-style tips tend to move faster; ball, needle, and related tips often support more controlled or stamina-focused plans.
How to evaluate a part
Ask what the part helps you do, what weakness it creates, and what the other two parts must cover.
