Beyblade X Samurai Calibur Guide

SamuraiCalibur 6-70M is the official name behind product code BX-45, released in Japan as part of the Beyblade X Basic line on August 9, 2025. It's positioned as the successor to the earlier SamuraiSaber 2-70L, carrying the samurai theme forward into a new blade-ratchet-bit combination. Multiple retailer listings agree on this date, though one retailer blog listed August 23, 2025 instead — if you're chasing an exact release window, treat that discrepancy as unresolved rather than picking a side without checking with your own retailer.

Blade, Ratchet and Bit

The set combines three parts, each doing a distinct job. SamuraiCalibur is the blade: a four-sided, square-profile Balance-type piece whose Gear Chip artwork shows a samurai wearing a kabuto helmet. The 6-70 ratchet contributes six evenly spaced protrusions at 7.0mm height, and the Merge bit (notation M) is the standout part — a dual-tip design that pairs a flat rubber surface with a sharp plastic center point in the same bit. Overall the combo is classed as right-spin, Balance-type. Per the Beyblade wiki, the Merge bit is the first Bit to use 18 gears instead of the standard 12, which makes it about 4 millimetres taller than a standard Bit and made it the heaviest Bit at its release.

Why the Merge bit matters in play

What makes Merge worth knowing about is that its behaviour depends on how it's launched, not just how it's built. A hard, aggressive launch engages the rubber tip and pushes the combo toward Attack-style movement; a controlled, gentler launch favours the plastic centre point instead, giving Stamina/Balance-style stability. Community discussion frames it as a bit that rewards a skillful launch and punishes a careless one — the same physical part can play two different roles depending on the player's hand. In practice, players report SamuraiCalibur doing well against pure Stamina-type opponents and holding its own against Attack types when the launch is precise, while dedicated Defense-type blades are consistently named as its toughest matchup.

As always, if you're bringing a BX-45 SamuraiCalibur to an organised event, it's worth a quick check with the organiser or the current rules pack that your specific copy and any substitutions are tournament-legal before you show up expecting to battle.
