Support BladeForums! Paid memberships don't see ads! Disclaimer: This unit was sent to me for review. Note: In order to avoid too much overlap of two otherwise similar products/reviews this TPT review work (2016 product) should be understood as supplement or follow-up to the TPT Slide Review (2018 product) posted earlier. Either contains comparative references to both products but it would have been too messy to compose one big comparison review. Summary. Let's start with my layman's constructional criticism: in the animated GIF's we are going to learn that the bottle opener could not have been designed any shorter to make the '4 blade notches enables 4 deployed positions' still agreeably possible. the nub for the blade notches is placed at the very right top corner of the titanium back plate, no millimeters of titanium space are wasted, allowing for a maximum of edge length to be exposed for the cutting task. the tool length lets the user keep the blade in the tool for the cap lifter functionality. great idea great design. chamfered grind makes flat head screwdriver (as is) slippery, i.e. less functional as screwdriver. it is straight-forward to mod it, though. because of the fat chamfers nearly everywhere, only one side of the tip of the screwdriver can be used effectively as general scraping tool; fortunately the tool shoulders (on one side) are sharp 90°-angled and could, for example, be used as striker for a ferro rod the millimeter-spaced vertical grooves at the bottom and top edge of the tool are too shallow to enhance the finger's grip or to function as wood file. while the bottom edge can be used as finger nail file, why not make a genuine metric ruler (with +1mm resolution) out of it? For the pro's and con's I am listing only the most outstanding relevant points, not every "feature". The Good: incredibly light weight (with installed razor blade only 24g w/o lanyard); and the overall dimensions similar to (and thinner than) two stacked regular keys, making it totally suitable for keychain-EDC very pocket-friendly carry on the keychain: fat chamfered edges, no pointy tips/corners, nothing pokes/catches/snags in the pants (not even the screwdriver or the bottle opener!) because of fat chamfers and rounded corners feels comfortable enough in hand fwiw for being that thin; nice build quality, no internal rattling noise totally safe and secure in the pocket, no accidental deployment possible in practice a 6-way tool: fire steel striker, finger nail file, mini pry bar, bottle opener, razor blade as cutter & scraper (imho the hex bit driver and the open-end wrench have extremely limited practical usage and sorry the screwdriver becomes fully functional only after a mod) no accidental blade retraction upon hard gripping during heavy duty tasks; (relatively) secure deployed position razor blade with 4 blade notches enables 4 deployed positions, blade with 3 notches enables 3, with 2 notches 2, etc, i think you're getting the point The Bad: price mini pry bar is on the thin side, probably not indestructible thin tool, difficult to get a secure (and safe) grip during heavy duty cutting tasks ojo! difficult to operate with gloves, too difficult to operate one-handedly The Ugly: nada. zilch. In the hand of a maker a trapezoidal utility blade can be used as a knife, a screwdriver, a sandpaper, a chisel, a marker, a carver, a shaper, and the TPT's bottom edge could be used as a cutting ruler. The TPT also lets you use the laterals of the deployed blade as scraper and backup striker for a ferro-rod. I did not enumerate all these potential features in the TPT Slide review because here, on the original TPT, it apparently comes more natural to manipulate the blade with two hands and eventually take it out. Unboxing / Misc / Disassembly. My unit was shipped in a small gray bubble-padded SFC-labeled envelope PAR AVION as CHINA POST registered letter, trackable through several sites, and reached me in less than 2 weeks. The tool and sheath came in retail blister packaging. Very commercial, wow. The leather sheath is bigger and also (with the two included safety inserts) heavier than the tool itself. A sheath for a keychain tool? Hmm. Or maybe it is for helping you not lose the tool, when you throw your stuffz in a duffle bag. But then the black color wouldn't be really helpful. The lanyard helps with the grip, ring finger and pinky would hold at it; alternatively, the two fingers would hold at the bunch of keys. The hex bit driver is nice to have i guess, if you have hex bits on you. The safety inserts don't become valuable imho until half of the dull edge has been sharpened to a razor edge. If i needed a dull edge for opening boxes, i'd simply use a regular key for the task, no? Other reviewers called the fork on the safety insert "gimmicky", i'm calling it "usable fwiw". The screws were tightened so firmly that only my iFixit driver could loosen them, i didn't have enough grip on the SHEK tool. I noticed that TPT Slide screws would be a bit too long on the TPT and vice versa, so one should not swap the T6 torx screws between the two tools. Note: Screws which are not tightened back firmly could get loosened after frequent operation of the locking mechanism. Me, instead of tightening them back firmly, i preferred to put a droplet of el cheapo liquid transparent paper glue in the three holes (threads) before inserting and tightening the screws; my el cheapo glue is totally harmless. I have loctite but sealing the threads with that would be overkill imho. Dimensions / Size / Weight. My measurements: thickness is 4.2mm, length 77.0mm, width 26.0mm. Weight of the tool alone is 21g w/o lanyard (on my +1g kitchen scale). A standard utility blade weighs 3g, so the total weight is 24g (w/o lanyard). That's lighter than an 1xAAA flashlight with Eneloop battery! The overall dimensions are such that you'd be hard pressed to find a similar keychain razor blade tool which disappears even better in your pocket or on your keychain; maybe the Screwpop Ron's Utility Knife 3.0 and that's about it. A safety insert weighs ~3.3g, the empty leather sheath weighs 19g. In comparison, my mirror-polished TPT Slide weighs 28g w/ razor blade w/o (lanyard+pocketclip). The Open-End Wrench. Not very usable in practice. This functionality got improved on the TPT Slide but it doesn't change the fact that in practice you'll get very little opportunity to make use of the wrench, if you ever encountered a (theoretically) fitting nut. A freestanding nut of this small size, never mind the size range, is an absolute rarity in our RL world prove me wrong! Imho we can safely ignore this potential functionality both on the TPT and the TPT Slide. The Mini Pry Bar. Thin bar, thin prying lip, short lever. Perfect for opening up home electronics plastic housings in your household, e.g. for repair purposes. Not so suitable for tough prying tasks, anything heavy duty, obviously. The mini pry bar is not a gimmick on the TPT but it should be used for mini tasks only. Owners who paid 69 bucks for the product will most likely know when to better not use the TPT as pry bar or mini pry bar. In comparison, the titanium back plate on the TPT Slide has a thicker, more solid construction with less cutouts which could compromise the structural integrity of the prying tool.
