Fein invented the handheld oscillating tool and released their MultiMaster back in 1986. At the time they decided to focus entirely on creating products of the highest quality possible. 23 years later they are retaining that attitude and have the most robust, easily usable handheld oscillating multi-tool on the market. The Fein MultiMaster Top system is quite simply the most well thought out, ergonomic and feature-rich oscillating tool on the market, even though Fein’s competitors have had over a decade to drool and tool up their own products now that the patent has expired.
