This looks really cool. What kind of kitchen tasks would you use this for?

Thanks! The knife would be used for cutting and chopping fruits and vegetables such as tomatoes, cucumbers, onions or anything that might roll around. Since it is designed for single handed use, the spikes grip into the fruit/vegetable, followed by one smooth slicing motion.
