### ⭐⭐⭐⭐⭐ Review
*by R***N on 23 July 2025*

Small and compact, can easily have in a pocket or small pouch. And the addition of no batteries required means less maintenance, the low price also makes it very affordable to replace should it became damaged or faulty. However I doubt the latter as klein is know for quality tools.
