Right now for me it'd be some Japanese chisels...or the new Veritas large plow plane.

If I didn't have the tools I have right now...it would be my Custom no. 4 1/2 smoother. Just a lovely plane to use.

What are the rest of you Galoots lusting after right now?
($400 is just an arbitrary number to keep the tool within the confines of most production tools, and to exclude any bespoke makers like Holtey or Sauer & Steiner etc.)
