Years of sharpening had left the full bolster extending below the
cutting edge. The bolster contacted the cutting board first, keeping
the heel from reaching the board and preventing the rear portion of
the edge from completing a cut.
This is one of my personal knives and has been used for many years. The
original Henckels blade marking had already worn away, so I also gave the
blade a gentle cosmetic polish while completing the repair.
Cosmetic blade polishing is not part of normal sharpening.
Polishing can fade or remove logos, etching, model information, and other
factory markings. It is only considered when specifically requested and
after the possible loss of those markings is understood.
Why bolster reduction may be necessary
Repeated sharpening gradually moves the cutting edge upward. A full bolster
does not wear at the same rate, so it can eventually sit lower than the heel
and strike the cutting board first.
When that happens, the last portion of the blade may no longer cut completely
through food. Correcting the problem requires removing steel from the bolster
and carefully blending the heel so the cutting edge can contact the board
continuously again.

Pre
Full Knife
The knife before repair, showing the original heel and bolster
relationship as well as age-related staining and surface wear.
Post
Full Knife
The restored knife after the bolster and heel were corrected,
the blade was cleaned, and a new cutting edge was established.
Pre
Heel Lying Flat
The bolster sits lower than the sharpened edge, creating a gap
beneath the heel when the knife rests on a flat surface.
Post
Heel Lying Flat
After reduction and reshaping, the heel can once again meet the
cutting board without the bolster interfering first.
Pre
Heel on Edge
Viewed directly along the cutting edge, the low bolster and
irregular heel transition are more apparent.
Post
Heel on Edge
The repaired heel now transitions cleanly into the reduced bolster,
allowing the cutting edge to function through its full usable length.
Corrosion cleanup and optional polishing
Light corrosion and staining were reduced during this restoration. Deep
pitting, scratches, and age-related marks may remain because completely
removing them could require excessive steel removal.
On this personal knife, a gentle polish was appropriate because the original
Henckels logo was already gone. Customer knives are not normally polished in
this manner unless the owner specifically requests it and accepts the risk to
any remaining factory markings.
Does the heel of your knife miss the cutting board?
A visible gap beneath the heel, food remaining connected near the handle,
or the bolster striking the board first can indicate that bolster reduction
and heel-profile correction are needed.
