My favourite chain tool
Well made and durable. Previously I've only bought used cheaper tools. This is far superior. I carry a lightweight tool with a few spare links in my saddle bag. I reserve this tool for my home toolbox.

Solid tool, as usual from park tool.
As is typical for park tool, undeniably expensive but it's a tool built for life for any home mechanic and id imagine even a fully loaded bike shop replaces it due to it being lost/stolen rather than worn out of damaged.

Good tool
I have broken my chain when on the trail, so I needed a good chain tool, now my chain never breaks!! But I met a young lady with a broken chain miles from sanctuary, I wiped out my trusty chain tool and fixed it for her, she offered to buy me a drink later, didn't want to be seen as an old pervert, so I declined, there's about 40 years between us, ho-hum, I recommend the tool though.

Skuwacz do codziennego użytkowania
Skuwacz łańcucha rowerowego działa poprawnie jest to urządzenie masywne/trwałe, dobrze się nim pracuje w warunkach stacjonarnych ale nie zabrałbym bo ze sobą na bikepacking z uwagi na wagę.

The price is worth the quality.
This is a great bike chain tool. It's on the pricier side compared to something you can buy for cheaper somewhere like Walmart, but as someone who broke two of those cheaper tools doing the thing they were intended to do before settling on this, just go ahead and invest in something of better quality like this. You won't be frustrated like me and break a cheap plastic pin getting a chain apart, which means there's no easy way of getting another pin out to remove a link, so you're out of luck until you can get to the store the next day to buy another of the same tool. Save yourself some headache, buy something like this that's of good quality and some replacement pins, and don't worry about the tool breaking on you every time you go to use it.

Muy buena calidad y muy preciso
Es una herramienta muy precisa y facil de usar a diferencia de otros rompe cadenas con los cuales me fue muy dificil o imposible cortar la cadena. Yo ando en BMX, cambie una cadena odyssey half link con esta herramienta y no tuve ningun problema, hice el cambio en 2 minutos.

Degelijk robuust en nauwkeurig.
Eerst had ik een goedkopere variant van dit tooltje, maar dat werkte helemaal niet en deed mijn ketting kapot en het tooltje zelf was na 4 pogingen ook verwrongen. Met dit prijziger tooltje daarentegen haal ik schakels uit mijn fietsketing als boter!
