hi guys, thanx for all the help.
codger, my knife looks very much like the bottom one in your post #4 and the far left (same knife?) in post #10. only difference is that the bolsters are like those on the knives in post #12.
lobo, i think scored, or line stamped is probably the right term since it makes more sense than the term pinched. thanks for the vocab lesson. i'll learn this stuff yet.
irv, i was not aware of the tang stamp other than the company name, etc. on the reverse, after a bunch of cleaning, i found that this is evidently not an 897 or an uncle henry, at all. the blade is stamped 825. so now i guess i need to research what an 825 is. maybe an open stock knife?
