Victorinox hard to beat
Victorinox is made by the same folks who make the Swiss Army knives. They have been in the knife business a long time, and make a good product. I own a Victorinox Chef's knife as well. Maybe the pro's need a heavier knife. As for me I am mostly a home cook, but also cook for church groups of up to 100+ people, and found it is more then enough knife for my needs.
