Register and Nuance
"刃" is a formal and somewhat literary term, often used in written language or in contexts emphasizing the blade itself. In casual speech, people might just say "ナイフの先" (tip of the knife) or "刀の部分" (part of the sword).
Common Mistakes
Learners sometimes confuse "刃" with "刀" (sword) or "ナイフ" (knife) itself. Remember, "刃" refers only to the cutting edge, not the whole weapon or tool.
