I purchased the square corner punch, but you can also buy one with rounded corners. I already have a rounded corner punch so I thought square would give me more options.
This thing is a lot larger and heavier than I expected. It's a two-handed punch and made quite solidly from metal, magnets and plastic, so it isn't the most travel-bag friendly if you like to punch-on-the-go. The top part comes off completely to allow you to position your photos/paper against a clear 3x4 window which I thought was a nice feature. The punch also locks down into a "closed" position for easier storage (about a 2cm difference in height)
Using The Punch
When placed on the punch, the paper/photo is held in place by magnets and you can tug the paper around through the magnetic field to get the right cut. I don't know if it is just the punch I got, but I found it to be very stiff at first, and I really had to put my weight behind it when punching down. I think this might get easier with time as the mechanism loosens up a bit, though.
I also found that every so often, the punch would get jammed into its closed position. I changed surfaces (from the carpeted floor to a solid table) and this helped stop the jamming, but made it a bit harder to push! I think it needs a dead vertical pressure, and a solid surface makes this easier.
The resulting 3x4 card itself is cleanly cut, and easy to remove through the clear window. I wondered why this was a hinged viewer at first, until I realised removing the magnetic top to grab the card every time sent little residue "punch holes" all over the place! Yep, as well as the card, you also get mini holes around the punched area (see photo below) I guess this is to make sure your photo stays put, but seems a bit overkill when accompanied with some very strong magnets! It also wastes a lot of paper :(
This punch absolutely saves time when cutting down photos and scrap book paper. It's well-made and I think it would last a very long time, as long as the blades remain sharp.
However, I don't like the mini punch holes. They basically mean that instead of 12 cards from a single sheet of scrapbook paper, you can get about 4/5 which is a HUGE reduction and paper isn't cheap.
I also think that the price is really off-putting. I managed to get my punch from WRMK at a sale price of £15 and I am happy with that price for what I get, but I think £30 is a bit steep, especially if the jamming issues never stop.
Do you have the WRMK card punch? What do you think of it? Are you considering buying one?
