I have a desire to learn detail work and Kolrosing so I bought these two knives to give it a try. I have been using a V chisel to try and make designs on my Kuksa handles and spoons. But the purchases of knives does not guarantee that you can carve anything other than a mess. I looked for videos on how to do kolrosing and was unable to find any. So its trial and error time . Del Stubbs has some great pictures on his page. http://www.pinewoodforge.com/kolrosed.pieces.html
Here are a few examples of what I can do now with my small mm V chisel but with practice I hope to be able to improve.
