We often grab a knife to take along for picnics or travel lunches - something small and sharp to cut an apple or cheese. We usually wrap the knife in a paper towel to protect us when we forgetfully grab it by its blade. This Messermeister Picnic Knife is designed for us and others eating on the go.
It has a safe plastic case that slides over the blade, with a button release that makes it extra safe, especially when you have children's hands reaching into your picnic basket. $6.95 at Complements to the Chef.
