Hello All, I found these years ago in the back of a garage of a house where my ex-wifes neighbor lived. She had recently passed away. Are they sharpening devices for butchers knives? They can't be files as they have no "roughness". Two are triangular[large and small] one is flat and one has a semi-circular side. Are they perhaps files that have not been finished yet? The wooden box has little spring-loaded clips to hold the tools in place. Note the label which suggests 6 possibilities. Thanks and Regards, Leipzig
