What do you get for the friend who has everything? Well, if that friend is a fan of perfectly crafted cocktails, take your cues from Jackson Cannon at The Hawthorne. The master mixologist and proprietor has designed, in partnership with Murphy Knives, the perfect bar knife. Available at The Boston Shaker in Davis Square, this knife is ideally suited for cutting citrus, notching or creating fruit twists and facilitating clean up (its straight edge can be scraped against the counter to clear away tipple-y debris). At $79 it might be a bit expensive (and pointy) for a stocking stuffer but with this little number at the ready, your giftee will be able to batch craft cocktails with the best of ‘em. Pick one up at online or at The Boston Shaker (69 Holland Street).
