Step 1: The knives and sharpening steel
Step 2: The basic pieces
This is the basic piece I used. Five are required. Each is made up from strips of oak scraps taken from old church furniture destined for someone's fireplace. The strips were glued together for a butcher block effect. I used a rotary planer attachment on my radial arm saw as a thickness planer to make pieces about 5/8 inch thick and smoothed them a little with a sanding block before gluing the five layers together. But, that gluing operation comes later.
The five pieces are in the shape of an elongated trapezoid. The long dimensions are 10 1/2 inches. The longer end is five inches. The shorter end is two inches.
