A Fuji EZ Keeper holds your lure securely, keeps it from tangling around the rod tip and keeps it out of bushes and branches as you walk down the trail. Many anglers hook their lure to the butt guide. I wouldn't, at least I wouldn't hook the point through the guide itself. You definitely do not want scratches in the guide inserts. Hooking the point through the "K" foot of the guide is probably fine, since it won't scratch the insert, but it is probably better idea to use a Fuji EZ Keeper, which keeps the hook well away from the guide.

For the Daiwa Wise Stream 50TUL, you definitely should use a Fuji EZ Keeper. When the rod is collapsed, the butt guide is too close to the rod tip.
Even with the extremely small Daiwa Presso Vega spoons, the distance from the tip guide to the but guide is too short for the hook to hold. Also, is definitely not safe to just reel the lure right up to the rod tip and let the hook wave around, free to catch anything it touches.

The Fuji EZ Keeper attaches to the rod easily. Wrap the O ring around the rod blank and over the "ears" of the Keeper. The Keeper folds up to hold the hook or down to be out of the way.
And in case you needed any more reason to use single hook lures, when the lure is hooked as shown in the photo above, the point is relatively well protected. If the lure had treble hooks, two of the three hooks would be exposed.

The Fuji Hook Keeper is the same item, packaged for sale in Japan rather than the US.
Earlier this year I couldn't get the EZ Keepers so I ordered directly from Japan.

The hooks are sharp.
The coffee's hot.
The fish are slippery when wet.
Seriously, all the hooks sold on Finesse-Fishing.com, whether packaged as loose hooks or attached to lures, are dangerously sharp. Some have barbs, which make removal from skin, eyes or clothing difficult. Wear eye protection. Wear a broad-brimmed hat. If you fish with or around children, bend down all hook barbs and make sure the children wear eye protection and broad-brimmed hats. Be aware of your back cast so no one gets hooked.
Also, all the rods sold on Finesse-Fishing.com will conduct electricity. Do not, under any circumstances, fish during a thunder storm. Consider any fishing rod to be a lightning rod! Fishing rods can and do get hit by lightning!
Whatever you do, do it with finesse!
