I decided to try out my new mini lathe with these knives. I had several wood species to choose from but decided to give it a real test. I took a piece of Red Eucalyptus from the firewood and milled it down to the size for pen blanks. Eucalyptus hits somewhere in the 1400's on the Janka scale. That's harder than most domestic wood in the US. Then I took the bad end of one piece and cut it down using these knives to build a push tool for assembling the pens. I tried out every knife in the kit, played with them a little and worked the eucalyptus down. As you can see, the project turned out well.Since I am using a mini-lathe, the small size of the knives worked as an advantage for me. They handled well and were very sharp. I will soon be turning pens. I hope to update this post in the near future with a Eucalyptus pen having been completed.The product arrived much earlier than projected. I was glad of that. The box was damaged in shipping. But, I didn't buy these for the box. Thanks for reading, Joe T.
