Goldedge bent

[Seaswood]

This was bought some time ago I have several satinedge that do well this blade although looked unused likely was dropped.
i have been going over it when I do other blades full sharpening sequence.
but I am wondering if I should of had someone straighten the blade instead of trying to sharpen over & over?
May not look too bad I checked with microscope not pretty.
i do tho like the rounded end, what would that be called.
some Satinedge blades are like that.

I would worry about all the stresses that have been put through that area. Does the wave extend quite a bit up? If it is fairly localized maybe try grinding past it and relating the heel? I'm sure someone will chime in, I tend to cut the cord on basket cases at that level.

 

[Seaswood]

Looks like there are two separate spots.

You should actually ask a moderator to move this post to the honing section vs the razor section.

I was wondering if it should go there,

moderator?

Can you repost your photo, the link is not working.

I don't think dropping a straight will bend it, they are too brittle. I suspect a bad grind or stress related warping.

Attempts to "straighten" that warp will very likely just crack the blade, rendering it useless.

That one goes into the display case I'm afraid. The warp extends all the way up the blade and you'd have to grind off a huge amount to get the concave side to the edge.

Can't tell how deep that deformity goes but it appears to be significant enough...honing past it is probably possible but not without a lot of loss in width. If the photo is making it look worse, then maybe it is salvageable.

Unbending that curve without incurring major issues is unlikely. The edge was intended to be a straight line but is now an arc; that path is longer than it would be normally. The steel can't be pushed back into itself to restore a straight line. Again, if the photo is distorting the damage, that's one thing but looking at the pic above at face value, I would pull the blade and maybe send it out for a regrind evaluation... or just toss it. Probably toss it.

Disregard earlier request, Photo link is now working after refresh.

Hard to say what happened to the edge, but the heel is badly in need of correcting. Reprofile the heel and move the heel corner (Red Arrow) away from stabilizer (Green Arrow). The razor has been honed on the stabilizer and possibly the tang with a heavy hand. (Blue Arrow).

The need for heel correction and honing on the stabilizer has kept the heel half of the razor off the stone. (Red arrow, existing end of the bevel)

The resulting honing caused excessive wear on the spine and looks like it was honed with finger pressure on the edge, in an attempt to force the heel on the stone, knife sharpening style. This at the least exacerbated the edge condition and may be the cause of the wonky edge.

I would first correct the heel, an easy 5-minute fix (HEEL CORRECTION – REPROFILING Made easy),with a diamond plate. Then ink the bevel with colored ink and see where the edge is contacting the stone.

You may need to remove the whole bevel and cut a new bevel, which is what I would do with high angle honing or bread knifing on a diamond plate. Then cut a whole new bevel. It is not as much work as it sounds and really you have nothing to lose, at this point.

Do tape the spine with two layers of electrical tape, there is no need to create more unnecessary and uneven wear on the spine. The tape will also compensate for the excessive and uneven spine wear.

What does the edge look like from toe to heel, looking at the toe, edge up. Can you take a photo from this angle?

 

[Seaswood]

There are two spots where it was visibly bent about a inch apart, it was not much.
but with a precision blade it does not take much.
On each side of the P.
i will try a end shot.
the Green arrow is pointing to now position on blade? Stabilizer?
okay so I need to slow down pay attention.

I suspect it warped during heat treatment, it's almost impossible to bend that type of steel after hardening without breaking it.

Probably un-honed because no one who knew anything about straight razors would have bought it new.

 

[Seaswood]

I may not have a diamond stone but I can get one.
hard to get focus on edge it is not pretty

 

[Seelector]

Yep your only option is to hone until you’ve hit straight steel. Looks like you’ll lose 2-3mm of width. Could be more or could be less, you don’t really know until you do it.

Read through @H Brad Boonshaft post on heel reprofiling. You need to grind away the heel of the blade so the profile matches the red circle. It doesn’t take long, the metal there is thin. I use adhesive backed 220 grit sandpaper stuck to a piece of tile.

 

[Seaswood]

I have several different type general stones one should work.
i May have to revisit my technique as this is trying to re-establish a edge.

the satinedge I have found is quite good a couple I think older versions one looks terrible but they both work extremely well. Better than the newer not so much used sharp blades.
maybe because of the profile of the heel?

 

[kcb5150]

You also need to be careful about crashing the tang into the stone.

 

[psfred]

Make sure you are not running off the edge of the stone, I don't think occasionally honing on the stabilizer will cut divots out of the edge.

Running off the stone and lifting the spine will.

I still say it's warped.

 

[Darth Scandalous]

Kinda looks like somebody tried to sharpen it on a belt. Especially given the spinewear is even and consistent.

 

[Seaswood]

This was damaged from what ever when ever, two more one showed up the spine was ground down the other similar.
I keep a cigar box of dubl ducks that I go through using & honing.
occasionally I have to redo one not often.
this I was doing when I was honing others as it showed up with two bends in the straight.
call it warped if you will it was not straight.
i will work on heel & keep honing.
