Richards Sheffield England fisherman's scaler approximately 4 1/2" closed and approximately 8" open with 3 1/8" blade. This pocket knife has ivory celluloid handle. Richard's closed in 1983 and I believe this knife is from the 50's or 60's. It is in extremely good condition with no signs of ever being sharpened. There is no wobble and very few light scratches. It snaps well open and closes well. Please refer to pictures for additional condition details. Let me know if you have any questions.
