you have enough to sharpen them just fine. now you need. thread, glue, dyes, rivets. snaps or buckles, beeswax, oils, a ruler or straight edge, strap cutter, stitching pony or clam, a hammer or mallet some hole punches would be nice too. these are for general leather crafting, specialty work like shoe making or saddle making takes various specialized tools as well. I'm sure I've missed a few necessities as well.
