    I’d like to purchase Amscope metallurgical microscope to see the edges, but I am a complete dummy about microscopes.

    Should I buy one with polarization? A while ago Clay posted awesome pictures with 2000X magnification. Amscope has 500X with polarization, but not 2000X with polarization. I am looking at models ME580T-PZ-2L and ME300TZB-2L-14M. Does anybody have experience with those?

    Just for inspecting knife edges for condition and sharpening progress the polarizing feature is really unnecessary.  Your not really examining the steel.   Your scanning the bevel to see the effectiveness of your technique to lay down scratch patterns.

    The least expensive scope I ever purchased is still my go-to favorite.  It’s simpler and less complicated to use.  Better, more feature packed, more expensive scopes, I found I spent my time fiddling and adjusting the scopes and their software and not sharpening  knives.  I use this plugable 2.0 at 800×600 resolution and high power.  It locks the image in quickly, and keeps it clear, which is impt using the scope hand-held as it’s slid across the knife edge.

    Thank you Marc! I’d like to see a micro bevel with clarity, not just a scratch pattern. Spending time for fiddling and adjusting is OK. This project is in my bucket list. Something like this image posted by Clay a while ago.

    Don’t misunderstand me.  The clarity is there with this scope.  When used properly, you’ll be able see the edge damage, defects and it’s condition when first clamping up the knife to decide your plan of attack. You’ll be able to see damage as small as pin point size chips and scratches.

    Once I get started, for me, it’s all about my progress through the grit progression and my consistency in applying my scratch patterns.   As I get down to micron and submicron grits I can examine my bevels and apex for remaining mini-defects and oversights I still need to refine.

    I’m able to see everything I need to see or, to see go away, to achieve shiny reflective mirror polished edges.  I can see the toothiness applied or the burr that remains using 0.1micron DLF.  That’s really as much scope as I need to achieve super sharp usable edges on my personal use knives.

    Remember this is only 200X power with a hand held scope on a knife clamped in the W.E., or just held in my hand.  Clay is using 2000X with the knife clamped in a stand microscope.  That power needs the stationary stability.

    I understand you may be looking for more then I’m working with.  If so, for that, I can not help.

    I believe those images of Clay’s are made attempting to measure the scratch patterns laid down by an abrasive to determine the depth of the scratches imparted in the steel and the distance between these scratch grooves.  He’s trying to determine if these scratch dimensions are consistent with the assigned abrasive sizes or grit sizes assigned for a particular sharpening stone.  This was part of an effort to place all the different grits and abrasive mediums on one universal grit chart arranging them coarse to fine and showing a comparison of their actual physical scratch patterns.  This is intended to help W.E. user’s to decide how to use multiple different abrasive mediums in their sharpening progression, to “mix and match” them so to speak, to use them in the best, effective order to achieve the results they seek. To do what Clay is attempting requires a better scope than we need for viewing sharpening progress and results.

    Ok. I thought that he was talking about a new post. Thanks, Marc.
