  • This item: Bench Dog® Tools No. 4 Smoothing Plane $111.99

Bench Dog's No. 4 smoother takes the thinnest of shavings for an exceptionally fine finish. Used skillfully, it can be the final step before finishing, and it also makes a good general-purpose plane or first plane for your collection. Quality materials, precision machining and solid construction result in a hand plane that's an absolute pleasure to use. The sole is precision ground flat to within a few thousandths of an inch. The blade is made from thick 1/8'' hardened carbon steel for reduced chatter and excellent edge retention. Solid sapele is used for the comfortable tote and knob, adding a touch of elegance. Each plane includes a case, sock, manual and a Certificate of Inspection with measurements specific to your plane for sole flatness and blade hardness.


  • Ideal for surface finishing and final smoothing
  • Ductile cast iron body for superior strength and resistance to impact

Why does the #4 Smoothing Plane work better than the #5 Jack Plane for final soothing of a surface? -- Or does it? The only difference in specs is the sole length and weight. The Sole length for the smoothing plane is 10 inches and for the Jack Plane is 14". The jack plane, being longer, is a little heavier. The sole width, blade width, blade thickness and material, bevel angle, and frog/blade angle are all identical. Given that the blade bevel and frog angle are the same, it seems the jack plane should be able to cut just as fine and smooth a surface as the smoothing plain. Please explain. Am I missing something? Thanks

BEST ANSWER: It has to do with the length of the sole. The longer the sole, the more it will ride over small imperfections rather than smooth them out
