The CT-08 uses a rotating blade system that presents a fresh cutting edge at each blade position — the CB-07 blade is the OEM replacement when all positions have been used and cleave quality begins to degrade.\u003c\/p\u003e\n\u003ch2\u003eWhy Cleaver Blade Replacement Matters for Splice Quality\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncreasing cleave angle:\u003c\/strong\u003e A dull blade produces higher cleave angles.
