That looks alot better than my first one! Nice job, you got some talent my friend! There are a couple of tests that are considered "standard" and can help you adjust your heat treat and temper as you go. One is making pull or push cuts on a piece of 1/2 inch hemp or sisal rope. Hold it firmly on a good cutting surface and start slicing. This will tell you how long you can expect to hold and edge and how well your edge geometry is for the task. A bowie or camp knife will not make as many cuts since it is a thicker blade/ bevel meant to chop. A thinner blade like a hunter or fishing knife will cut more. You can also learn alot form the edge flex. Get a round brass rod or whatever and clamp it in your vice. My friend uses a smooth steel, I use the back or my tourque wrench. Run the edge of your knife across is in the same motion as you would sharpening it. Use enough pressure so that you can see the reflection of the light on the edge deform or "flex". 2 or 3 passes on each side will do the trick. If the edge gets a burr or rolls the edge is to soft and might have been to hot in the tempering cycle. If you see or feel small chips it is to hard and the temper wasn't hot enough. You have to play with it to get it just right for the steel you are using, but if it doesn't roll and doesn't chip you got it! Hope this helped. There is alot of knifemaking talent on this forum so keep the questions comming!
