Don't go to home depot. Go to a welding supply store or even HF and get some brazing rod. For the price of one rod at home depot, you will have enough to make 100 knives.
With Maple, I go to 320 with dry paper, then I start to use tung oil and saturate the wood over several days. Once saturated, then wet (tung oil instead of water) sand with 400 wet, 600 wet, and then 800 wet paper. Polish with fine steel wool, and apply bees wax.
