This is a test of the Thorn XV, 125 gr broadhead. Here is summary of my 2022 Testing Procedure & Scoring w/ the scores of the Thorn XV posted in parenthesis as well. Total Sevr 2.0 Score: 86.46 = 9 Golden Arrows 1. Flight Forgiveness (20%, 20 pts) This is not just a test of how heads fly out of my bow, as it was in the past. With a well tuned bow, properly built arrows & good form, almost every head flies well. That's why in the past most heads got a flight score of 9 or 10. But that doesn't help those who may not have perfectly tuned bows/arrows/good form. So now I am gauging Flight Forgiveness. This is based on how the head flies for me, how well it spins, how "sensitive" the flight is to imperfections, & the exposed surface area of the blades. The max score of a Mech is 10 (20 on 20 pt scale) & the max score of a Fixed is 8 (16 on 20 pt scale). 2. Cut Size (20%, 18.88 pts) The more tissue being cut, the more lethal the head, all else equal. The entrance cut, total cut, & width of the cut (a crucial variable for bloodletting) are all scored: The entrance cut size is compared to a standard of 2.5" then that fraction is weighted to 7% of the score. (2"+.3"/2.5" x 7 = 6.44 pts) The max cut size is compared to a standard of 2.5" as well, then that fraction is is weighted to 7% of the score. (2.3"/2.5" x 7 = 6.44 pts) The max cutting diameter is compared to a standard of 2.0", then that fraction is weighted to 6% of the score. (2.0"/2 x 6 = 6 pts) 3. Blades (20%, 17.18 pts) Initial sharpness (9%, 225 grs=9.75/10=8.76 pts ) & Edge Retention (9%, +100 grs=8/10=7.2 pts) are measured using the Edge On Up Sharpness Tester. The pressure needed for a blade to cut thru a copolymer wire is measured in grams. Edge Retention is the loss of sharpness after the head is shot in Penetration Test 1, thru 1/2" MDF and 2/3" rubber foam mat & Clear Ballistics FBI gel. For every 50 "grams" of sharpness lost, 1 point is deducted from 10. What are some sharpness scores for common edges? A butter knife takes 2000 grams of pressure to break the co polymer wire. A new high end cutlery edge: ~ 375 grams of pressure. A utility razor blade: 200 grams. Based on the many broadheads I have tested, here is my scoring scale: Out of the Box Sharpness: 0-200 gr: 10 201-300 gr 9 301-400 gr: 8 401-500 gr: 7 501-600 gr: 6 601-700 gr: 5 701-800 gr: 4 801-900 gr: 3 901-1000 gr: 2 1001-1100 gr: 1 1101+ gr: 0 Ease to resharpen or replace blades is judged & given 2% of the score. (7/10=1.2 pts) 4. Penetration (20%, 13.15 pts) There are 3 penetration tests: Pen Test 1: 1/2" MDF, 2/3" rubber foam mat, Clear Ballistics FBI gel. Depth of penetration is compared to a standard of 9" & weighted to 9% of the score. (5.75" = 5.75 pts) Pen Test 2: Layered cardboard. # of layers penetrated is compared to a standard of 70 layers & weighted to 9% of score. (42 layers=5.40 pts) Angled Penetration Test: How effectively does the head penetrate 1/4" MDF covered by carpet at a 45 degree angle. This accounts for 2% of the score. (2/2pts) 5. Durability (20%, 16.25 pts) Each head is shot thru 1/2" MDF 3 times. Its condition is judged 1-10 after each shot & weighted to 12% of the score. (10/10 = 12 pts) If a head survives that, it is then shot thru 22 ga steel plate twice. Its condition is judged 1-10 & weighted to 5% of the score. (8/10=4.25 pts) If a head survives that, it is then shot into concrete once. Its condition is judged 1-10 & weighted to 3% of the score. (0/10= 0 pts) Steel plate & concrete are certainly not "realistic" mediums, but they do reveal the outer limits of a head's durability. BONUS: Heads will be rewarded bonus points for special, intangible features such as: rotation, no O rings/clips for mechs, extra thickness, hole size, other unique designs, etc. +1 extra forgiving flight TOTAL XV SCORE: 86.46= 9 Golden Arrows Price of Thorn XV: $13.32/head Grading Scale: 90-100 10 Golden Arrows 85-90 9 80-85 8 70-80 7 60-70 6 Special Notes: Please check out my sponsor, Stay Sharp Guide. https://staysharpguide.com/ or @Innovative Outdoorsman They make excellent broadhead sharpeners.
