Restoring Filarmonica in bad condition

[Brains]

Just finished restoring this Filarmonica
Had to straighten bevel line and re-set bevel
Honed and stropped, will give it a try tomorrow

Congratulations. Remember, looks don't shave.

Thank you
Had the first shave, a delight, can understand the hipe about Filarmonica, smooth, really smooth

Wait until you try a thinly ground one.

You can improve that edge by reprofiling the heel. Note the wide bevel in the belly and narrow bevel at the heel and toe and massive spine wear over the stabilizer. The toe may not even be honed.

If you put the edge on a flat surface, you will see a bit of concave and even S shaped edge, (long red line). Note the perpendicular red line where the heel edge ends. The spine wear indicates the razor has been honed on the stabilizer. This will keep the edge from sitting flat on the stone, creates an uneven bevel, concave edge, and a sharp pointed heel.

Because the heel is not making full contact the honers of the past have added pressure, to force the heel on to the stone and created the current wavy edge.

Reprofiling the heel, moving further from the stabilizer and will allow the razor to sit flat on the stone and straighten the edge. It also removes the pointed heel that will eventually become a hook and will cut you. The edge of the heel will move from the perpendicular red line to the blue line.

It is a simple 5-minute fix on a diamond plate. It will make future honing much easier and create a straight edge.

One can see that quite a bit of the razor width and spine has been honed away. Note the position of the etch on the belly and how uncentered the etch is. This has been a long-standing problem that previous honers have attempted to “fix” with pressure. A simple heel correction could have eliminated a lot of needless wear and produced fine shaving edges. It still can.

I would also add at least one layer of tape, possibly two to compensate for spine wear.

Thank you so much
So the idea is to file the stabilizer in order to correct the heel? What do I need to do to get the heel corrected?

Wish I knew this earlier,
Thank you both Brad and SilverLifter
