Cable Matters 110 Punch Down Tool with 110 Blade - Ethernet & Keystone Punch Down Tool for Cat 8, Cat 7, Cat 6A, Cat 6, Cat 5e, Cat 5 Network Cables - Ideal for Network Installations, Data Centers & Home Wiring Projects

I was torn with this item whether to rate it 4 or 5 stars.Pros:~ cheap~ reversible blade, one side cuts, the other does not.~ adjustable spring, however so far in my experience I am not sure where you would need to adjust the spring.~ Some people are suggesting that they aren't getting clean cuts from it. This the first punch down tool I have every used, but from my experience it seems to cut fine. I realized immediately the effectiveness of the cutting action is really dependent on how you hold the keystone jack and how sharply you punch the wire down. Initially I tried punching down against the wall, but after a practice round, I found it functioned better when I placed the keystone jack down on a flat hard surface like the floor. Half the time the wire would cut cleanly, and half the time it would score the wire to that a very light bend or touch would cause the end to fall away. Maybe if you are a network specialist and very experienced with a variety of punch down tools you would expect it to fully cut away the wires with no further intervention every time. But for me in my home...having to gently "pluck" the wires off after punching down seems fine.Cons:~ it does feel like a cheaper tool. That is sort of an intangible concept, but you can tell when holding something in your hand by the mass and the solid feeling of it how well its made. This does feel a bit light and flimsy, but that sort of explains the low price. So I decided to not deduct a star for this.In summary, given that I will likely only use this tool one time while installing all my home network, the cost seems to justify the functionality and cheaper feeling of the tool. I would much rather spend $10 on a limited use tool than $50 for a professional tool merely for the convenience of not having to barely touch the wires after punching down to get them to fall away. I am a very satisfied DIY user.Here are the supplies I used to built my media infrastructure:Keystone plates = http://amzn.com/B006IKGHVC and http://amzn.com/B006IKHAZYBlank Keystone = http://amzn.com/B006IKH0EAKeystone Mounting Bracket = http://amzn.com/B003JQL0S8Cat6 Keystone = http://amzn.com/B004D5PFGWHDMI Keystone = http://amzn.com/B0039L3P86Coax Keystone = http://amzn.com/B003099HOICat6 Cable = http://amzn.com/B0049KV52E (the cable this review is written in)Coax Cable = http://amzn.com/B0069F4H3GCoax Right Angle Adapters = http://amzn.com/B00DUW3Y7GWall Mounted patch panel = http://amzn.com/B000HZES42Cat6 Crimp connectors = http://amzn.com/B00BS92DCAStrain Relief Boots = http://amzn.com/B000I20B86Crimp Tool = http://amzn.com/B0000AZK4GPunch Down Tool = http://amzn.com/B0072K1QHMCoax Crimp Tools = http://amzn.com/B003J7YOTO
