I made my own rather recently (arguably not the most visually appealing one out there, but works perfectly), but I think if you get a design that work well than it would surely be interesting to many - it is not easy to find a really good magnetic holder. And, imo, it is the most comfortable way to keep the knives (and does display them nicely too)
From my
personal point of view - the following properties are relevant:
- the holder should have 2 rows of magnets so that the knives do not rock around
- the magnets should either be close to each other (if these are round magnets some 10 mm gaps are OK - I did it this way ) or ideally have no gaps between them (rectangualar magnets) - the knives then do not tend to slide sideways to a spot where the mag. field is stronger.
- the holder should be wide enough - I bought one that was just 4 cm wide and it did not feel safe with longer knives - it went back promptly. I made mine 8cm wide and it is great.
- the holder should either be thick enough, or there could be a spacer (maybe as an accessory upon buyer's request) that allows to keep the front surface of the holder at at least 4cm from the wall (mine is around 4.5cm with the spacer) - it allows grabbing the knife without hitting the wall with your knuckles.
- it should look great
(I failed miserably in this regard) - the bars you show above look very nice indeed.
EDIT: seems like I came a bit too late to the party :scratchhead: , but I could still offer to test one for free :lol2:
