Phil, simply amazing. I was starting to learn engraving along about those same years myself. The only book i ever found at that time was Meeks The Art of Engraving which was actually quite helpful except for his favorite graver being the onglette which i could never get to cut a decent line of any kind without huge burrs and just couldnt stand it. No matter how I tried sharpening it it never cut any better for me that a cold chisel. Later learning about the wonderful square grave which is just about all i use for everything . I about gave up engraving over that damn onglette!
Great start you made there, your amazing talent showed itself early and has only gotten better over the years. Now lets JAM!
