Finding ferrules for tool handles is often difficult. One of the easy things to use is a copper pipe coupler. Often one couple can be used to make two ferules. They are also easy to shape on my anvil with a dome tool on the anvil:

This handle used a full 1/2" coupler.
Yesterday at Lowes the 3/4" stop couples were at $1.27 each. The 1" slip couples were $5.59. That doesn't make sense to me. The slip couples do not have the pressed ring around them. This means another step in making them. The pressed in ring makes them easier to cut with a hack saw.

The Lowes web site shows a different price but the 1" is still 3X the cost of the 3/4". My first thought is maybe the 1" were repriced before the 3/4". This was my reason for picking up four of them yesterday.
Should maybe pick up some 3/4" end caps. The also make good ferrules for tool handles.
