Apparatus facilitating a cutting operation, comprising in combination:

• (a) a knife;
• and
• (b) a hand-mountable cutting board utensil for protecting a thumb of a hand from the knife during cutting against the cutting board utensil, the hand-mountable cutting board utensil comprising,
• (i) a cutting board for disposition between the thumb and an index finger of the hand, said cutting board having an exposed cutting surface for orienting toward the index finger and a second surface for orienting toward the thumb;
• and
• (ii) a retainer having two lateral sides and being configured to receive and releasably retain the thumb along a longitudinal length of said retainer, said retainer being attached to said cutting board along a portion of said longitudinal length of said retainer, said longitudinal length of said retainer being greater than a majority of a longitudinal length of said cutting board;
• (iii) wherein said exposed cutting surface is uninterrupted for protection of the thumb during cutting against said cutting surface;
• and
• (iv) wherein said cutting board includes first and second portions that extend transversely to a direction defined by said longitudinal length and that extend respectively beyond said two lateral sides of said retainer, each said portion having exposed, oppositely facing front and back surfaces.

Apparatus facilitating a cutting operation, comprising in combination:

• (a) a knife;
• and
• (b) a hand-mountable utensil for protecting a digit of a hand from the knife during cutting against the utensil, the hand-mountable utensil comprising,
• (i) a shield having an exposed cutting surface;
• and
• (ii) a sheath having two lateral sides and being configured to receive and releasably retain the digit along a longitudinal length of said sheath, said sheath being attached to said shield along a portion of said longitudinal length of said sheath, said longitudinal length of said sheath being greater than a majority of a longitudinal length of said shield;
• (iii) wherein said exposed cutting surface is uninterrupted for protection of the digit during cutting against said cutting surface;
• and
• (iv) wherein said shield includes first and second portions that extend transversely to a direction defined by said longitudinal length and that extend respectively beyond said two lateral sides of said sheath, each said portion having exposed, oppositely facing front and back surfaces.
