Hobby Knife

It's like an Xacto knife, only better. We use these extensively when working with PCBs. These small knives work well for cutting traces, scraping ground pours, and guiding hair-like wires into their proper place. Excel knife comes with aluminum handle, one ultra-sharp blade, and safety cap.

    Haha. I like how adhesive bandages are included in the related products. Good to be honest.

  • They have these at my local hobby store, but for some reason I feel like I need to buy them from you guys.

  • saccade / about 15 years ago / 1

    How's about selling us replacement blades too? I once lucked into a box of 100 for a few dollars at a hardware stuff, but haven't seen them since.

    • Member #331641 / about 12 years ago / 1

      You will get all kinds of replacement blades here:


    • Madbodger / about 13 years ago / 1

      They should show up now under related products. :)

    • naneau / about 15 years ago / 1

      yeah, one blade won't laste forever :)

      • deepblue / about 15 years ago / 2

        On the other hand, it's two bucks. You might as well just buy a new one.

        • CaseyK / about 14 years ago / 1

          Replacement blades are usually around $2 for 5 and $30 for 100. You can buy them just about anywhere

  • davr / about 15 years ago / 1

    watch your fingers closely when using these! it's all to easy to slice a nice big cut in your finger if you're not careful

    • Yep - I got a scar on my thumb to prove it!

      • SomeGuy123 / about 13 years ago / 3

        I count about 10 scars on my hands, arms, and fingers from exacto knives. These things are evil.

It's a hobby knife! It cuts stuff.

It does what it should and was a good purchase. There is not much else I can say about a hobby knife. ;)
