The No.02 is Opinel&';s smallest folding knife (since the discontinuation of the No.01 in the 1930&';s). Small in stature, but highly efficient, the keychain version of the No.02 follows you everywhere. This tiny knife is excellent for small tasks like opening letters or cutting papers. This is a very small knife (under 2 inches when folded!); please review the size before purchasing. Due to the size, this knife does not feature the ViroblocA(R) safety ring. We also have this knife in tomato red and sky blue. Specs Blade Length: 1.36 inches Steel: Stainless Overall Length: 3.25 Inches Weight: 0.18 oz.
