This is a well designed and robustly constructed tool, but is it the best one for the job?

The cutting blades are powered by the squeezing of fingers using one hand. I am an elderly man with very strong hands but quickly found the use of this tool to be very tiring: it is fine for from 5 to 8 minutes of use. Good for a quick trim of a very small area of grass, but not of anything thicker. A further issue, I am 5 foot 11 inches in height. Will this equipment work for a really short person, since it has a long handle?

In buying this item I was trying to avoid buying a more expensive weed wacker with rapidly rotating nylon cord,  but I wish I had paid the extra dollars. For the small area this Fiskars cutter will handle I feel I would be better off using a traditional, longer and more robust bladed cutting tool, one where the power of your arms and shoulders are used. If you can't bend at all then this Fiskars item, while not really satisfactory, may be the way to go. And then the question still remains: do you have quite strong hands?
