Mine would be a Wolverine grinding Jig; it is a special tool that helps me sharpen a variety of lathe tools and drill bits by hand on one of my many bench grinders.
I will tell you that the new snap on ratchets, along with the Matco 88 and wright ratchets are a joy to use.
The sure grip technology of the wrenches that are made today are up there on my list of tools that I am impressed with.
The lower Decibel ratings for the IR air guns along with the rubber texture handles.
New cordless tools coming out all the time just fantastic and getting lighter and more powerful.
One tool I would love to get my hands on is the extra long Matco wrenches but at over $400.00 for a set I must wait, but still they look like a winner in my book.
