MVT = Most Valuable Tool
This is a topic that comes up regularly in the online woodworking forums and there are as many choices as there are woodworkers.  What tools are most valuable to you?  Are they the ones that you use on each and every project, or the ones that perform some unique and irreplaceable function?  Are they the ones you've owned forever or the latest addition to your arsenal of tools?  From time to time I'll post profiles and reviews of some of the Most Valuable Tools from my shop.  I think the results may surprise you!
