How it fits the work

The knife presents an angled edge that can meet a row of contacts from the side. Choose a narrow D08 for an isolated pad if the knife edge would extend near another part. The tip still requires a compatible T18 pencil.

Care for the working face

After cleaning, cover the working face with fresh solder before putting the iron away. Hakko recommends checking for pits or an altered working profile when a tip stops wetting properly. Care instructions

Questions before buying

Would I use the knife to reach a single pad beside another lead?

A knife edge can extend toward the next lead. Use a narrower chisel or point when the area is crowded and reserve the knife for a row with enough side clearance.
