I bought these clippers about four years ago and they came with a replacement blade. Our two kitties keep their nails somewhat short with their scratching posts, but occasionally we have to clip off the talons to protect the couch and make their fights fair. These particular clippers work so well that I didn't want to throw them out, but the second blade was so dull I worried it would hurt the cats. So I did a search and found replacement blades at a great price on VetDepot. They shipped them quickly and my kitties are nicely trimmed again!
