Amazon offers Prime members the Morakniv 4.1" Companion Fixed Blade Outdoor Knife in Orange for $8.48 with free shipping. (Non-members can spend $49 to bag free shipping; otherwise, it adds $5.58.) That's $2 under our mention from three weeks ago, $3 off list, and the lowest total price we've seen for any Morakniv knife. It features a Sandvik 12C27 stainless steel blade and plastic sheath.
Of note, it's also available in other colors with prices starting from $9.99. Also, these items are marked as shipping in up to two months or temporarily out of stock, but are still orderable.
