Swingline 3 Hole Punch, 20 Sheet Capacity Three Hole Puncher 3 Ring, Adjustable 2-7 Hole Paper Punch, LightTouch Low Effort, Black & Silver (74030)

Works a treat

Love this hole punch. My old one is over 20 years old and was sticking and not creating a clean hole. The new one works like a champ! There are NO directions on or in the box on how to unlock the lock so that you can use it. Other people have mentioned this too. I tried You Tube videos, but they didn't explain it well enough so I looked for written directions on the web. The following is a direct copy of what I found that worked in a second plus a few extra helpful words! The key is: You have to press down on the handle/punch arm with one hand while sliding the locking device, at the base of the handle/punch arm, to the unlocked position. That is all it took to work well! To unlock a Swingline hole punch, you need to: Place the punch on a firm surface. Hold down the punch arm and move the gray piece, at the base of the punch arm, to the left. It will unlock. You must have the arm held down to lock or unlock.

Just what I needed for Marr sheets

This is a great machine.... It lines up the paper easily, has a strong handle. If I could improve anything, I would add a stronger latch for the page size adjuster... I currently only use it as a 11" puncher, so I just tape it to this one so it doesn't slide.

Excelente perforadora no batallas
