I found these on Pinterest when looking for Wood carving Patterns . They have little Videos thru out the Pages and when I saw the Demo I thought I would give it a try . Used it today on Mahogany and it cut thru easy and Deep without any effort . They have 3 Flutes and not like the other ones that have many Flutes and get plugged up . Cost me a little less than $ 25.00 for the 3 Sizes . It takes from 2 -6 Weeks to receive , I think it's worth the wait . It takes a lot to impress me when it comes to Tools , these little Buggers do that . The Mere Fact that I'm posting about it tells it all . Oh! 1-IMG_0001.JPG the Shank is 1/8 " Merle
