I have a magnetic knife rack which is mounted inside a cupboard
door.

The knives are not as securely held as I would like. What is the
best distance and orientation for a second magnetic rack placed
parallel to the first one in order to help hold the same set of
knives as firmly as possible? I can't tell by hand.

The picture above shows two long magnets on a knife rack and each is
sandwiched between two strips of metal. I *GUESS* one long thin
surface of a metal strip is N and the other is S. (Is this
correct?)

Each rack has two long magnets about an inch apart and maybe they
are aligned in a particular way such as "N+S N+S" (going from one
side of the knife rack to the other). Or could it be "N+S S+N"?

Based on maximising the magnetic holding power of a knife placers
across both racks:

(1) How close to the first rack should the second rack be placed?

(2) Does it matter which type of magnetic pole on one rack is
nearest a particular magnetic pole on the other rack? Or is the
distance of the two racks (from question 1 above) too great for the
magnetism of one to influence the other even when a knife is places
across all the metal strips?

Thank you for any info.

Get a single knife rack with enough holding power ?

The one I used to have had a very powerful grip (was not cheap #20
odd), so much so after a year or two the two magnetic strips started
pulling out when you removed a knife (with all the other knives
attached) and after gluing the magnets back in starting ripping the
plugs out the wall.

Was replaced with knife holder in a drawer as we suffered from dirt
and other kitchen "splatters" accumularing on the knives as there
were out in the open.
