"I got a bag of Dremel type/looking tools recently but I don't have an idea what some of the items are or what they go on. Does anyone recognize some of these?
I thought this might be a saw blade that fits into an exact knife but the teeth go all the way on each end.
Are these some kind of hot blade sculpting tools?"
These are Xacto routing and woodcarving blades from the Xacto Deluxe Woodcarving Set
You will need the red handle to hold them. They will not fit the standard silver Xacto handles.
