The handle is cross-hatched for secure gripping, with a hole for a lanyard. The thumb rest is ridged for positive handling. The blade provides a serrated area for cutting cardboard or other heavier material. Portable, compact, convenient and practical for the home, work, office, camping. By Lansky Sharpeners.
