How it fits the work
The angled knife offers an edge for reaching along a row of exposed contacts. Compare the 4.7 mm width to the space beside the row. If only one small pad is exposed, the T15-IL uses less lateral space.

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
Can I use a knife tip for one small through-hole joint?
The knife can contact a joint at its corner, but compare the blade clearance beside the lead. A smaller point may be easier to place if the rest of the edge would overlap other pads.
