A finger guard which is made of impervious hardened plastic. It is open at the proximal end and tapered to closure adjacent the distal end. A compressible-extensible slot extends in axial alignment of the guard from the proximal end thereof to a position which is short of the absolute distal end. The guard slot, while closed during nonuse, is expandable into variant expandable widening positions, which positions are determined by the size of the carpenter's index finger. There are two factors which secure the splinter guard to the index finger. The first is by a resistance compression of the guard upon the finger, causing a friction fit. Secondly, as the asymmetric interior configuration of the guard conforms to the distal joint and fingernail extension of the finger, this causes a clamping effect and friction fit as the finger is forced into protected position. The guard is adaptable to either the left or right hand index finger without modification. Its utility extends to power sawing and board measurement.
