Today's assignment, four inches of steel.

Yikes this might take a week!

I have a client's Buck that is way overdue because of the charity, and my SIL's medical scissors, she's a nurse.

Fortunately I also have tiny little stones. Now if I had better eyes...

Is that a real buck knife or a knock-off? Something doesn't look right. Perhaps it is possible the blade has been re-shaped? Maybe the end at sometime was broken off. It looks more like a drop point as opposed to a clip point that normally seen on the 110 knife.

I don't appraise 'em, I just fix 'em.

I asked the client about the tip and he assures me it's the original. No matter who actually made it, it sure is good steel. I had to use a half-size Atoma 140 just to shape it.

Ahhh, the good old days.

Before I was a polisher I was considered a "tinker." Kind of a European title for a guy who fixed and polished kitchenware. And actually, this is the work I like to do, and I'm still shaping.

This is a Buck 505. It's not like a machete where four or five bad cuts go unnoticed. You remove metal from this knife and it's gone.

The two biggest problems on this little knife were, one, the left side bevel was cut bigger than the right side, and two, the tip turned up too much like a "pig snout."

That might seem like a small issue, that is, until you're ten miles from home with a sliver in your hand and your tip is dull.

I'm going to dress down the spine a bit near the tip, match the curvature and polish it to the same grit level so the repair is seamless.

And I'm slowly nibbling the right side to slightly widen it while the cuts take the left side down to match it. There are already points on the edge that are very sharp.

OK, now you have described it I can see it is a 505. Thanks for the clarification.

I think I now know why I've never been banned. I'm the only one with an obsidian brick, and knows how to use one.

The knife the client sent me had a bit of a "pig snout." It looks like his previous sharpener tried to re-make the tip by eating metal away from the bottom. The correct procedure is to carefully modify the spine down.

I'm about halfway done. First we make a new point, then make sure the curvature of the spine is uniform, then we polish the spline of the knife to cover the obsidian scratches.

Like Chuck can tell you, a splinter in the finger requires a knife with a point.

I'll print up the completion shots when I'm done. Then I'll be ready to use mid-grit stones.

Little knives have to be perfect, too!

Okay, I finished the rough work with obsidian, and then made sure the curvature of the spine was correct and tip was a needle.

I will now try to quit shaking and use my first mid-grit stone...

So... you drop the drop point down? Interesting, but sensical. I suppose you could start the drop further back and add some curve, if you're looking for more pointiness. So what's all this about obsidian?

Obsidian is simply "hard lava." It cuts better than anything. But more to the point it's as big as a house brick. It gives me a long "runway" to smoothly run a rugged or chipped section down for shaping.

The knife had a slight curve anyway in the spine, I just "massaged" it to better make a better tip.
